This bi-fold closet door track kit is constructed of various materials, including a roll-formed track that comes in a white-painted finish. This kit provides all necessary hardware for hanging one bi-folding (2-door) panel system. The hardware can be used with individual door panels that have a maximum weight of 30 pounds each. The top-mount track measures 35-3/4 inch for easy installation into 48-inch Wide closet openings. This is a factory-cut length to help simplify the installation process. This kit features three non-mortise hinges that mount to the jamb surface and over the vertical door stiles. Mortising into wood is not required. Use this hardware kit to enhance the beauty of a closet with bi-folding doors that fold open, in place of a single hinged-swinging door. Note: Bi-fold door panels are not included, but are sold separately by others.
