This by-pass closet door track kit is constructed of a galvanized track, with other steel and plastic components. It features double-J tracks for the installation of a 2-door panel system. The track length is pre-cut to 47 inch to minimize the need for cutting, and it is commonly used with wooden door panels measuring from 3/4 inch thick to 1-1/4 inch thick. Each kit includes an adjustable bottom guide (constructed of a steel base with adjustable plastic tips), brass-plated stamped-steel finger pulls and installation instructions. This kit will safely hold doors that weigh up to 75-pounds each.
