Prime-Line Bottom-Mount Drawer Guide Kit R 7211

They feature a self-closing design that commences at the final 2-1/2 in. from the end of the 19-3/4 in. long tracks when closing. The maximum load capacity for this kit is 75 lbs., and it fits most bottom-mount drawer systems. This kit cannot be cut down to fit smaller drawer depths as it is designed with a positive stop at the ends of the fixed tracks, and because the rear rollers (11/16 in. diameter wheels) on the sliding tracks are fastened to the ends of the drawer-mounted track pieces. These bottom-mount drawer slides can be installed in drawer cabinets with face frames and without.
