Johnson Pocket Door Frame Kits fit doors up to 5 ft. wide by 9 ft. high. They work on all doors 1 1/8-in to 1 3/4-in thick and weighing up to 125 lbs. Heavy-duty ball-bearing hangers are available for sliding doors up to 200 lbs. The track's box shape and convex rails make it impossible for hanger wheels to jump off. Special keyhole slots allow for removal of the track without tearing out the wall. With Johnson's hanger clip system, the door can be removed for painting or staining after the drywall and trim are in place.
