Whether youre updating cabinets or youre building a project from scratch, mounting drawers is always a challenge. The slides have to be level, straight, and positioned properly, or the drawers wont operate well. The drawer slide jig takes the guesswork out of the process by indexing with the cabinet frame (or side on frameless cabinets) for perfect alignment.The jig supports the drawer slide level and straight while you install it in the cabinet. Then, the jig clamps on so it protrudes from the cabinet to support the drawer while you drive screws into the drawer box. With this jig, youll know that your slides are positioned correctly, so your drawers will operate smoothly. The drawer slide jig consists of 2-brackets that clamp in place inside the cabinetone on each cabinet sideandalignwith the cabinet face frame (or with designated marks on frameless cabinets) to support the drawer slide as you drill mounting holes. The brackets are also reversible to protrude from the cabinet, and then clamp in place perfectly aligned to support the drawer as you mount the slides to the drawer box, too. The drawer slide jig works with almost all types of drawer slides, including ball-bearing, epoxy-coated, andundermountslides. All you need are the slides youll use, a clamp, and the drawer slide jig, and youre set to install drawer slides just like the pros.
