Everything you need to know about Hydraulic Doors for Aviation, Agriculture, Industrial & Architectural use

The Advantages of Leasing an Original Hydroswing® Hydraulic Door

The outstanding engineering, space saving quality, ease-of-use and increased productivity delivered by the Hydroswing® is now available through our new “game changing” door leasing program.  This is an industry first for hydraulic doors, and Hydroswing® is proud to once again be in front of the pack.

 

So why should you lease a hydraulic door?


• Technology is moving and changing. Outdated bi-fold, slider and roller doors are quickly becoming obsolete (and in some cases, dangerous.) Even if you don’t have the cash on hand, you can still have the original and best hydraulic door on the market.
• If the door is used as a part of your business, there is the potential to enjoy a tax break because the lease payments will be fully deductible.
• The Hydroswing® door lease requires ZERO down.
• Low payments! This will free up your cash to invest back into your business.
• Total lease payments are almost always less than the original cash price of the equipment.
• Whether you choose a short-term lease (two to three years) or a long-   term lease (four to five years), your payment will only be for the selected term.
• At the end of the lease and you’ll have a $1.00 buyout or FMV (Fair Market Value) buy out and the warranty that you had in place will assure your Hydroswing® door unit is as good as the day you first installed it and opened it.

 

 Pre hung, pre assembled and ready to install, when fitted to existing buildings, the Hydroswing® single panel hydraulic door adds strength and valuable return to buildings which might have been previously seen as past their useful life. In the event you build new to replace the old, unbolt the Hydroswing® and simply refit your Hydroswing® to your new building, (or Hydroswing® can do this for you).


For ZERO down and payments starting as low as $49.99 per week, you truly can have it all: Single panel door simplicity, powerful and smooth hydraulic rams, solid tube steel construction, pre hung, no top or bottom rails, no sectional seals, no wasted wall or outside area conflicts, push button operation, exceptionally low operating and service costs.


Change your door…It’s easier than ever. Give us a call!

 

Introducing Hydroswing® Leasing -The Best and Original Hydroswing® Hydraulic Door Can now be Leased as Equipment

It’s no secret that equipment leasing is a leading choice for the agriculture, aviation and industrial sectors.  With equipment being the mainstay, owners have looked to leasing to help the cash flow crunch while allowing them to quickly acquire the latest technology. Since 1960 private fixed investment in equipment increased from $29.7 billion to almost $1 trillion in 2012. In 2013, that number continued to rise. Nonetheless, the economy has made it difficult for businesses to part with cash, even though they are in need of new equipment. Leasing solves that problem. And now Hydroswing® enters the arena and expands the possibilities across all sectors. A door is no longer a door. Thanks to Hydroswing® Leasing, any hydraulic door we manufacture can be considered a piece of working capital equipment.

 

In agriculture alone, leasing of equipment exceeds $6 billion in annual volume in the United States. In aviation, approximately 30% of the world’s aircraft are leased, and that number continues to increase. Leasing works and Hydroswing® is on board. Hydroswing® Leasing is the first program of its kind to offer hydraulic doors as equipment: No money down, low payments ($49.99 per week) and a $1.00 buyout at the end of the lease. There will always be more old buildings than new, and with a Hydroswing® lease, it’s easier than ever to replace your obsolete door system and enjoy the efficiency and advanced technology of the original Hydroswing® hydraulic door. 

 Leasing a door is not as complicated as it seems. It’s a painless process that preserve your line of credit, let you keep your cash flow in place and can immediately add value to your business.  In addition, lessees can take an immediate write-off of dollars spent rather than waiting for equipment or storage facilities to depreciate over several years. You’ll also have the option of deduction 100% of your lease payment as a business expense. To make the package complete, a Hydroswing® lease allows for opportunity to eliminate or minimize shipping and install costs. It’s a “win win” all the way around.

 

 Hydroswing® Leasing is a game changer for industry. Hydroswing® has over 7,000 doors in use and is being manufactured in ISO 9001 approved global manufacturing plants worldwide. Hydraulics are the most effective door choice. The advantages: Less than 70% of the moving parts of the bifold door and 50% less moving parts than sectional, bottom rolling, or top hung doors with 95% less maintenance costs. The Hydroswing® easily retro fits to replace the bi-fold, bottom rolling, top hung, sectional or fabric doors, and is ideal for new builds, steel, post and frame or block structure. Now everything is possible with a Hydroswing® door.

 

Stepping into the Future of Agriculture

15. May 2014 11:14 by Hydroswing in Agriculture, Farm Doors, General

A couple of centuries ago, 90% of the population in the United States lived on farms and produced food. Today, farmers who produce cereals, fruits, vegetables, meat and dairy, only make up 2% of the population and still provide to the masses. To keep up with this ever growing demand, agriculture has turned to modern machinery and technology. In 1940, the data shows that one farmer could feed 19 people. By 2010, that number had increased to 155 people. Changes in equipment, biotech breakthroughs for crop production, and modified barns and storage facilities have allowed for vast improvements throughout the industry.  

 The bottom line: Farms are growing in size because of increased efficiency, and hydraulic doors are playing a huge role. Hydroswing® is playing a huge role. It’s important for all farmers to keep their valuable machinery locked in and secure, and the Hydroswing® single panel hydraulic door is the best choice. The Hydroswing® is operated by two dual-acting hydraulic rams powered by a single or three-phase motor and pump. This in itself provides an extra layer of safety because the Hydrowswing® is impossible to operate without access to the control unit, making it far more secure than other types of doors. And, with almost 100% seal-ability, our door can be easily retrofitted to existing buildings or fitted to new builds for the ultimate in efficiency for all agricultural building or shop doors.

 

 What’s on your farm? Bi-folds? Roller doors? Sliders? Unlike those, the Hydroswing® will not pop out of its rails, rust away, flap in the wind, or allow birds to fly in via the gaps around the door slabs. The Hydroswing® seals all the way around its own frame and if required for food regulations, can be made 100% varmint/bird proof. With Hydroswing, there is freedom to “open end” or “open side” any building, providing unrestricted loading and maneuvering for composting, silage, grain storage, feed/transfer sheds/buildings and farm shops.  The overhead clearance also allows for multiple load discharge saving valuable supplier transport time between loads… all going straight to your bottom line and ROI on your investment in the Hydroswing® single panel hydraulic door system.

 

If you have special coverings/sheeting and sealing requirements, the simplicity and strength of a Hydroswing® allow you to have the door covered in the same as the walls maintaining insulation levels for better efficiency and cost effectiveness over cold winters.

 

Step into the future of efficiency with Hydroswing®. Our doors can be fitted to post and frame , pole barns, stick, steel (PEB), tensile, Quonset, brick and block structures with little or no alteration to an existing building for retro fit or total simplicity when designing your new building to receive the totally “pre hung” Hydroswing®.

 

 

 

 

 

It's Time for a Hydraulic Door

Retrofit is defined as a “modification to equipment that is already in service using parts developed or made after the time of the original manufacturer.” When it comes to doors (or walls), it’s easy to retrofit almost any opening with a Hydroswing® single panel hydraulic door. Whether you’re in aviation or agriculture, you’ve seen bad doors. Broken (and dangerous) bi-folds, torn fabric sliders, self-built disasters, and inefficient rollers and stackers can cost more than they’re worth to repair. Chains, pulleys, straps and too many parts can invariably lead to a break down and possibly an accident where someone may be injured or even killed. So isn’t it time for a change?

The original Hydroswing® hydraulic door is the ideal replacement for any kind of door on any kind of structure. Because our pre hung design, we can retrofit both large small building doors with little or no impact to the existing building. These minimal load and reaction levels to existing structures allow a simple removal of old door and, in most instances, no additional structural work. Customers are seeing the benefits of “going big” and increasing height and width to maximum clearance.

Cost effective, safe, and accommodating in sizes up to 150’(45.0 m) wide  X 40’(12.0 m) high, our hydraulic door is being retrofitted in everything from commercial aviation facilities and private airplane and helicopter hangars to barns, agricultural centers, sheds and machine shops. The Hydroswing® is operated by two dual-acting hydraulic rams powered by a single or three-phase motor and pump. This in itself provides an extra layer of safety because the Hydrowswing® is impossible to operate without access to the control unit, making it far more secure than other types of doors. Simplicity, strength, ease of use and reduction in moving parts, plus use of cladding (which makes the door match the thermal characteristics of the building) are among the top reasons customers are making the switch to Hydroswing®. The sophistication of single panel hydraulic doors is now part of everyday door use for facilities large and small across the U.S. and around the world.

Replacing old facility doors with the low maintenance seal-ability and strength of a Hydroswing® is a smart, safe move. With almost zero in life service costs (creating a fast and high return on investment) the Hydroswing® is ready to go “pillar to pillar” and right to the header. The wider you go with a Hydroswing®, the better value it becomes. Isn’t it time to step into the future and retrofit your outdated door?

 

 

 

Ordinary to Extraordinary - Architectural Hydraulic Doors

14. April 2014 14:34 by Hydroswing in Architectural Doors

Architecture is constantly evolving… The trend in contemporary architectural design is to unite indoor and outdoor living spaces. With hydraulics in play, the functionality of doors and walls completely changes.  The Hydroswing® single panel hydraulic door system has become a blank canvas for the adventurous architects who specialize in high profile homes, commercial buildings and other special applications. In the past, architects were limited by how doors and walls function, but now the possibilities are endless. Walls up to 150' (45m) wide and 40' (12m) tall can be converted into artistic, useful and cost effective hydraulic doors that can create a unique and completely functional indoor/outdoor experience. With almost 100% seal-ability, design dynamics with a Hydroswing® hydraulic door are revolutionizing the way architects can create buildings and homes.  

Think of what can happen when walls become doors and doors become walls. Architectural problems can be solved and boundaries can be moved. Innovative design can be incorporated into existing structures (or new builds) and the overall schematics of outside walls can expand. The Hydroswing® for architecture can be built to totally change anything from a single wall (or door) in a custom home to an entire commercial building. Where sliding windows and bifolds used to be standard for restaurants with outside patios, hydraulic doors can now be used to enhance light, maximize space, and will revolutionize the way architects include outdoor environments in the scope of their design. With the touch of button, the single panel door can transform hotels, stadiums, bars, restaurants, garages, homes and any other kind of structure that wants to “move a wall.” The added bonus: With the door in an “up” position, shade and protection are immediately created.  

The simplicity and safety of the hydraulic door removes the need for cables and counter weights used in so many ambitious architectural projects and curved facades. The Hydroswing® isn’t a “knock off” of an agricultural door – ours is the original and most sophisticated design on the market today. Engineered for performance and precision, the door can be easily installed to match building profiles with glass, wood, or heavy and ornate finishes. Hydroswing® doors lift easily and quietly with ease from the power of the hydraulic single panel door system. We can customize any installation and the sky’s the limit in terms of design. Our hydraulic cylinders can be powder coated or chromed to match or complement the interior door colors to seamlessly connect indoor and outdoor spaces.   

Hydroswing® is the industry expert in silently and effortlessly moving structures, and we offer a new frontier for imaginative and leading edge architects around the globe.  

 

 

 

 

 

 

 

 

Are Bi-fold Doors Dangerous? You be the Judge.

The bi-fold door is once again in the news… and once again, it’s not good. Over the years, this kind of door has been linked to countless accidents and multiple deaths. On April 1, 2014 it happened again. According to CBS news in Minnesota, “A northern Minnesota man died Tuesday morning, officials say, after his jacket got caught in a large door at his work. It happened at Bagley Hardwood Products at around 8:40 a.m. The 41-year-old Fosston, Minn., man was standing next to a 40-by-20 foot bi-fold door as it opened. He got caught in some cables and pulled up to his death, the Bagley Police Department said.” Read the full article here.

 

In 2002, according to the US Department of Labor, “one of five lifting, hoisting cables came unfastened at one end of a bi-fold door, apparently because the saddle clamps had been installed improperly. One cable, immediately adjacent to the loosened cable was missing entirely, and the door began moving downward on the right side. The tilting caused the door roller to come out of its track. The lower portion of the door then struck Employee #1. He was taken to a local hospital where he was later pronounced dead.”

 

The photos below were taken from a recent bi-fold breakdown at Apollo Aviation, LTD at the Brighton Airport (Shoreham-by-Sea, West Sussex, United Kingdom). The existing doors were only three years old and one had fallen down completely as a result of wire cable failure, the other was an accident waiting to happen. Having narrowly missed the operator on site, Apollo wanted to quickly dispose of a potentially dangerous situation and start new with a stronger, simpler, safer hydraulic door solution.

 

The bi-fold door filled a need when it was first introduced to the market. It was the only game in town and seemed the logical choice for anyone looking for a door for their facility or hangar. There weren’t other options available, but now there are. Everything is different in the door world. Technology has improved, safety is a concern, and the bi-fold doesn’t make sense. On bi-folds, the pulleys and drive chains are exposed to the stress of constant movement and run the risk of slipping out or breaking down. The awkward fold, with its pulleys and straps, are cumbersome and can clearly be dangerous. Is it really worth the risk to have a bi-fold door? 

 

Hydroswing® Hydraulic Doors are a single panel hydraulic solution with 70% less moving parts. Our zero drop two-way Hydrolok system also assures the door will never fall should there ever be a loss of power. No cables. No pulleys. No Straps.

 

The choice is yours.

 

 

Biomass and Renewable Energy – A Market on the Move

Biomass energy is a hot topic. With a consumption increase of over 60% from 2002 to 2013, it’s easy to see why this sector is growing at such a rapid rate. Biomass is defined as “biological material derived from living, or recently living organisms. Both plant and animal.” Even though wood is considered to be the most prolific source of biomass energy, agriculture is currently producing huge amounts of biomass residue that can be converted to energy.  In 2013, half of all the renewable energy consumed worldwide came from biomass, with the U.S. number coming in at 5%.  (That 5% is enough power to accommodate close to a half a million homes.) The U.K. and Europe are already on the fast track to successful biomass energy platforms, and it’s catching on across the globe. According to recent reports, the use of biomass for energy could change the face of agriculture and provide farmers in the U.S. alone up to $20 billion in new income.   

 

The goal is to convert crop residue, manure and other agricultural byproducts into renewable energy sources. As farmers are learning how to capture and store these resources, they are gaining new revenue streams by producing energy while reducing disposal costs. According to Ag Energy Solutions, farmers can profit from “manure, corn stalks, woody-brush, or even weeds and grasses. By utilizing more of the biological material that grows on the farm, farmers can gain more value from each acre. And because biomass is renewable, and it’s easy to replace harvested trees or crops; these energy-rich waste materials are sustainable indefinitely.”

 

In addition to large, industrial facilities, farmers are beginning to construct buildings (within the guidelines and regulations of their rural area) specifically designed to house biomass. These multifunctional structures are made to store and protect the contents from moisture while creating space to burn and/or transport the material to biomass processing plants.  And Hydroswing® is there too. Our single panel hydraulic doors offer almost complete seal-ability, and with the wide variety of size options, they are the right door at the right time in the right sector.  

 

A current article in Biomass Magazine stated the “USDA Farm Service Agency recently announced the expansion of its Farm Storage and Facility Loan program, which provides low-interest financing to producers. With regard to bioenergy, the loan program can provide low-interest funds to build or upgrade permanent facilities to store eligible commodities, including renewable biomass.” 

With the ability to retro fit to existing buildings or apply to new build, the Hydroswing® adds size, ease of use and value to the processes in the biomass and renewable sector and can easily withstand the rigors of waste and recycling.  Pre hung in its own frame, the Hydroswing® can deliver zero load and reaction to the building is required to be fitted to a tensile or none structural building. Whether high cycling rates or long periods for seasonal storage and holding buildings, the Hydroswing® hydraulic door provides a greater array of working and process efficiencies than traditional sectional, overhead or roller doors with industry leading ROI.

The way we capture and use energy is changing.  The E.U. is already dedicated to the cause and has a goal of 20% of their energy being created by renewables by 2020. The U.S. is catching up and hopes to have 25% dedicated to the same faction by 2015. Hydroswing® remains on the cutting edge of all sectors of industry by providing a product that will easily adapt and play a role in existing facilities and new facilities that are being built to promote this commitment to new energy.

 

 

 

 

 

 

 

 

 

 

 

 

The Bifold Hangar Door… Inferior by design

Technology has moved on from wires, cables, pulleys and straps. The world is becoming simpler and safer. Hydraulic doors will soon be the only logical choice for not only aviation, but for agriculture, architecture and mining sectors as well. From a safety perspective, by its very nature, the bifold door is outdated and potentially dangerous.  We recently completed an installation in the U.K. that demonstrates exactly why bifolds are an endangered species.  

 

We were called us about replacing two doors at the Brighton Airport (Shoreham-by-Sea, West Sussex, United Kingdom). The existing bifold doors were only three years old and one (at the Real Flying Company) had fallen down completely as a result of wire cable failure, the other (at Advance Helicopters) was an accident waiting to happen. Having narrowly missed the operator on site, the owner wanted to quickly dispose of a potentially dangerous situation and start new with a stronger, simpler, safer hydraulic Hydroswing® door solution. The operationally unsound bifolds were products of Express Hi Fold Ltd. (a known knock off of an American product by a similar name) and rely on wire cables connected to a chain driven winding axle drum.  With such a high number of moving parts, the risk of failure increases exponentially.

 

 

 

 

 

Hydroswing® was an easy choice for Apollo. Our hydraulic Hydroswing® door is a single panel, has greater strength through design and steel size, 70% less moving parts than the substandard bifold, and is now manufactured in several ISO 9001 facilities around the world, including Great Britain. The door dimensions at Shoreham 60’(18.28m) x 17’(5.18m) and 55’(16.76m) x 17’(5.18m) respectively, were quickly retrofitted with Hydroswing® which in turn immediately provided an additional three feet of tail clearance. Our zero drop two-way Hydrolok™ system also assures the door will never fall should there ever be a loss of hydraulic power.

 

 The bifolds that were torn out have no frame so the retro fit was simple. (It usually only takes two days to fit any opening.) The Hydroswing® is built to fit easily pre hung in its own frame directly into the rough opening and welded straight to the header and uprights of the building. The vastly superior Hydroswing® also provides peace of mind when it’s open, closed or moving: No wires. No straps. No chains with axles or cogs. Most bifolds require supplementary contraptions to hold them in place while closed. Not the Hydroswing® - with almost 100% seal-ability, the door remains tight. These two Hydroswing® doors at Shoreham also incorporate our patented Bow Truss Technology, providing leading edge strength and aesthetics worthy of an architectural install. This special truss also gives “at a glance” certainty of the origin and integrity of this latest generation Hydroswing® hangar door system.

 

 The current trend shows more and more aviation facilities stepping away from the old and now outdated bifolds in favor of the safety, simplicity and effectiveness of Hydroswing®. (Note: A number of the well known Bifold manufacturers are trying to copy and emulate the Hydroswing® design. Keep in mind if it’s not from Hydroswing®… it’s not a Hydroswing®.) We proudly boast over 7,000 Hydroswing® in service and a growing number of bifold replacements and retrofit orders are coming in on a regular basis. Hydroswing® continues to change the general aviation hangar door sector for good. The Hydroswing® hangar door systems are the right choice:

  • 70% less moving parts
  • 100% improved seal-ability
  • Almost Zero Maintenance
  • Zero Drop Safety with Hydrolok™
  • 1m (3’.0) recovered clear height
  • 100% better looking
  • Adds value to the building
  • 90 MPH wind rating standard
  • Full drawing pack per door
  • Patented Bow Truss Technology
  • 2 day retro fit on most buildings

Commercial Hydraulic Doors Plus Industrial Hydraulic Doors Equal Solutions by Hydroswing

28. February 2014 10:41 by Hydroswing in Commercial Doors, General, Industrial Doors, News

Until now, a wall was a wall… enter Europe’s largest single panel hydraulic door. This gigantic manufacturing masterpiece is creating a revolution in terms of construction possibilities. Now walls up to 150’ (45m) wide and 40’ (12m) tall can be converted into useful and cost effective hydraulic doors. With almost 100% seal-ability, this conversion will forever change the face of commercial and industrial structures around the world. Hydroswing® has broken the size barrier and is charging into the large commercial door and industrial door market.

 

In December of 2013, the oil platform manufacturer, Heerema, needed something unique – a 115’ (35m) x 20’ (6m) hydraulic door for their Hartlepool facility in the north of England. “They knew Hydroswing® had the technology to design something of this magnitude, so naturally we got the call,” comments Alan Clark, International Sales Director for Hydroswing®. “We are very excited to have built this. We have always identified industrial and commercial usage as core sectors of our market and now that we have done this, we see the opportunity to change the way buildings deliver efficiency to their users.”  (The door was manufactured in Preston, England at an ISO9001 facility.)

 

 Before the option of this door, openings were restricted. Structures with needs this wide had to rely on steel rolling doors or sectional applications. The option of a single panel hydraulic door changed everything. The massive opening capacity, teamed with expanded vertical clearance and an almost air-tight seal, essentially creates a movable wall. In turn, the enhanced building efficiency (EBE™) reduces both costs across the board.

 

Hydroswing® was also called to task to provide a solution for Airbus in England. They were looking for a specific product for the Main Wing paint booth for their A380 Super Jumbo and wanted something that would be seated well enough to the floor that it would have the efficiency of a wall but the capabilities of door. We were able to manufacture a 57’ x 28’ (18 meters  x 8.5 meters) door that immediately matched their needs and retro fit their existing Durr Paint Booth in only five days. The seal-abilty of the door was so tight their reduction in electricity on extraction fan speed alone generated a return on investment (ROI) in six months.

 

Hydroswing® is overcoming space and size hurdles in the commercial and industrial sectors at a rapid pace. New projects in the works include a “door within a door” allowing for a smaller single panel installation within the confines of a 150’ (45m) main door allowing a wide array of multi-use possibilities.

Hydroswing® is single handedly changing the way people use doors in commercial and industrial settings. Our ability to design and create solutions for large industrial doors and large commercial doors will leave a lasting impact on productivity, efficiency and cost effectiveness.

 

Adaptability and Compatability - Hydroswing in Agricultural Construction

16. February 2014 09:16 by Hydroswing in Agriculture, Farm Doors

Post frame construction has its deep roots in agriculture. This kind of building came to prominence in the 1930s. Poles (usually telephone poles which in turn lead to the name “pole barn”) were sunk into the ground and steel roofing and siding was put into place to complete the structure. This was a short list for foundational material and it simplified the barn construction process. The telephone poles were later replaced by chemically treated sawn posts, then metal plates were introduced that connected the trusses and roof spans began to increase. Later, laminated posts made the scene and all the buildings were able to go taller as well. Today, post frame construction is still extremely efficient and is used worldwide for an array of projects, and remains the leading choice for agricultural and storage buildings.

There are a number of door choices that go hand-in-hand with post frame construction, but if you consider maximum opening dimension, least impact on building, maximum strength and sealability, lowest in service life costs, reliability, massively reduced moving parts and greater safety as the driving criteria... the single panel hydraulic door system will make the most sense. The agriculture and farming industry revolves heavily around hydraulics, so it’s easy to see why the Hydroswing® has become the premier door for farm machinery sheds big and small.

The post frame build can vary tremendously depending on the size and scope of the end structure. Hydroswing® can fit and/or retro fit almost any pole barn or post frame building with doors as large as 40' tall to 150' wide. If you need reduced building height/cost WITHOUT reduced door opening dimension, reduced part count in the structural mechanism of the door (no pulleys of any kind), integral pre hung frame with little dependence on building structure for strength, the ability to clad with more options than simply a 28 gauge steel sheet, have the same thermal properties as the building walls, almost 100% sealability to frame, self install simplicity, little or no in life service costs and lifelong reliability, as well as limitless window and man door options… then Hydroswing® is your answer. And, the Hydroswing® door is a perfect solution for replacing slider doors and roller doors. You can also enlarge your existing opening by replacing an inefficient bi-fold door.

 

Pre engineered metal buildings (PEB’s) have also been prominent in agricultural settings. The structures originally became popular during World War II for barracks and maintenance facilities that required no welding and could be bolted-up for simple construction. After the war, the industry continued to blossom. With the power of computer aided design (CAD), today’s metal buildings can be applied to almost any non-residential use. The Hydroswing® fits easily into new construction or is the ideal choice for replacing an outdated or beyond economic repair door such as a bifold, slider or top hung.

 

 The concept behind Hydroswing’s strong, single-panel, hydraulic design was born and bred by the demand for a more efficient door from the farmers and ranchers in the rural area. Hydroswing® quickly became the door of choice for savvy ag industry professionals across the country. Although the Hydroswing phenomenon now reaches across a variety of industries, the agricultural customer remains the backbone of the business.  Hydroswing® doors are engineered specifically to provide a cost-effective solution to meet the demands of the agricultural industry. Hydroswing® delivers strength, efficiency and reliability, utilizing the same hydraulic technology that you use on your heavy equipment every day to get the job done. Why would you trust anything less for your doors?
