Why Replace a Bifold with a Hydroswing®?

Replacement Door Compatibility

Hydroswing® can replace all Bifold hangar and large building doors with little of no impact to existing building due to the pre hung design, replacing the unframed Bifold "slabs" from all the Bifold door brands, adding strength, security and reliability to steel, post & frame, brick or block aircraft hangars and other buildings.

The Hydroswing® retro fits:

- Schweiss Bifold Doors (cable & strap)
- Hi-Fold Bifold Doors (cable)
- Erecta-Tube
- Welbuilt
- Aerodoor (Hi-Fold)
- Express Hi-fold (UK)
- Door Engineering
- Wilson Doors
- Home Built or Unknown
including any other brand of Bifold big or small, which has wires, straps, counterbalances, chains, pulleys, lock down devices and arms to increase clear opening.

Several Bifold Manufacturers seeing the change in market demand from their strap or cable Bi-fold doors, are offering an inferior single panel hydraulic alternative.


Picture paints a thousand words!

Remove the need for extra header steel work, or the need to heat or cool extra air in unused hangar space!
