Whether you're building production cabinets or just a single set for your home or shop, this drawer slide mounting tool will greatly simplify the process of positioning your slides accurately to assure smooth gliding drawer movement. The Kreg NZ03 Magnetic Drawer Slide Mounting tool uses the intersection of the cabinet stile and rail in face frame cabinets, and the cabinet side in frameless cabinets as a reference point from which to position a slide perfectly parallel to the drawer opening. Simply place a metallic drawer slide into position on the base of the tool, (magnets hold the slide in place) align the tool where the stile and rail meet as shown at left, and drive the screws. Perfect alignment every time! Patent Pending.
