This sliding barn door hardware kit adds a sleek, space-saving solution to bedrooms, living rooms, bathrooms, and other areas. Built from heavy-duty carbon steel with a black powder-coated finish, it is designed for long-lasting strength and resistance to rust and chipping. The smooth-rolling J-shape rollers and bearings help the door glide quietly and steadily. It fits single sliding barn doors up to 30" wide and 1-3/8" to 1-3/4" thick. Installation hardware is included, but the door itself is not included.
