Abstract
Abstract This is a two-panel folding door having one panel hinged to a door jamb and a second panel pivotally connected to the swinging side of the first panel. Special pivot brackets on the upper and lower ends of the second panel have adjustable clamp means to vary the overlap of the two panels according to the width of the doorway opening. Different width adjustments may be made in the top and bottom pivot brackets to fit an opening which is wider at the top or bottom.
