Universal Drawer Slide Jig aids in installing drawer slides of almost any type, including ball-bearing or epoxy-coated side-mount slides and even center-mount slides. Jig features a locking wedge that holds the slide securely with out slippage. Press the jig against the face of your cabinet and your slide is positioned perfectly level, with the proper setback. The jig can be clamped in place if desired, and it also features an adjustable rod that references off of the face frame rails or cabinet bottom for fast, repeatable height settings.
