Hangar door parts are not interchangeable between door types. A bifold, a rolling, and a hydraulic door solve the same problem three different ways, and almost none of the moving hardware crosses over. Identifying your door type first is the fastest way to order the right part and avoid a return.

The three hangar door types

Bifold doors fold horizontally into two leaves and are raised by steel cable or polyester lift strap running to a drum at the top of the opening. Rolling doors stay vertical and travel horizontally on ground-level wheels and track, driven by a motorized operator. Hydraulic doors are a single rigid panel hinged at the top that swings out and up on cylinders, forming a canopy over the opening.

How to tell which door you have

Watch it open. If it folds in the middle into two stacked leaves, it is a bifold. If it slides sideways along the building, it is a rolling door. If the whole panel stays rigid and lifts outward and up as one piece, it is hydraulic. If the door is already stuck and you cannot cycle it, look for the giveaways instead: a drum and cable at the header means bifold, wheels at ground level mean rolling, and cylinders at the jambs mean hydraulic.

What each door type shares

Weather seals, brush seals, electrical controls, and festoon cable components work across all three. Everything load-bearing does not. Cable, drums, and lift straps are bifold and rolling only. Wheels, casters, and axle assemblies are rolling only. Hinge assemblies and cylinder safety blocks are hydraulic only.

Hangar door types: common questions

Can I use bifold door parts on a rolling door?

Some parts, yes. Weather seals, brush seals, power buttons, limit switches, and SOOW cord are common across door types. Anything that carries the door's weight is specific to the design and will not cross over.

Which hangar door type is easiest to maintain?

It depends on cycle count more than design. Bifold doors have cable or strap that wears at the drum. Rolling doors have wheels and bearings that wear at ground level. Hydraulic doors have fewer moving parts but concentrate load into the hinges and cylinders.

I do not know my door manufacturer. Can you still help?

Usually. Most of what fails is standard hardware rather than proprietary parts. Send us a photo of the door and the part you are replacing and we will identify what fits.

Do you carry parts for doors that are no longer manufactured?

Often, yes. We custom fabricate cam followers, axle assemblies, hinges, and other components to specification. Send the old part or a dimensioned photo and we will quote a replacement.

Not sure which door type you have?

Send a photo and we will identify it and the parts that fit.
