THE SCHWEISS hydraulic bi-fold door can be fit to an existing building without revamping the building's supporting structure. The one-piece hydraulic door features a self-supporting header frame for added flexibility. The door is available in almost any size and can be adapted to any new or existing building. Low, minimum 4-in. headroom means a builder can work the door into a structure where lack of headroom may have been a problem.
The hydraulic doors are pre-built with a special bottom truss for added strength and rigidity.
Suggested retail price is around $4,000, depending on the size of the door. Contact Schweiss Bi-Fold Doors, Dept. FIN, Box 220, Fairfax, MN 55332, 800/746-8273, visit www.bifold.com or www.freeproductinfo.net/fin, or circle 192.
