Schweiss Bifold Doors manufactures the entire freestanding header. You may retrofit it to your building endwall or sidewall. The freestanding header is a quick and easy way to prepare your building for a bifold door. It consists of two side columns and the main header frame.
The freestanding header must be attached to the building and the building must be able to support the vertical and horizontal weights of the bifold door. You must tie the header and side columns to your building and provide a solid footing under the legs of the freestanding header.
