The new Superstructure Triple-Leg Stand-Alone Door from Schweiss Doors features a tripod leg design that transfers the door weight to the footings that support the hydraulic door, eliminating the need for additional side columns from the building manufacturer, offering a significant building cost reduction. The hydraulic door and framework are designed to help support the building structure. It’s a free-standing door that has its own superstructure framework attached and can be added to a new or existing building. Comes pre-assembled, pre-welded and pre-hung from the factory within a pre-squared frame, saving hours of installation time.
