The Kreg Magnetic Drawer Slide Mounting Tool simplifies the work of positioning your metallic slides to ensure smooth gliding drawer movement in cabinets. It uses the intersection of the cabinet stile and rail in face frame cabinets, and the cabinet side in frameless cabinets, as a reference point for positioning a slide perfectly parallel to the drawer opening. Simply place a metallic drawer slide into position on the base of the tool, which uses magnets to hold the slide in place, align the tool where the stile and rail meet, and drive the screws for a perfect alignment every time.
