Conductor for the installation of drawers. It is suitable for both framed and frameless cabinet furniture. It has special stops and tabs for precise alignment. You know what else is cool? This conductor has a large clamping area. You can securely clamp it to the cabinet and it won't move while you're working. This conductor can be flipped upside down! When you attach the rails to the cabinet, it faces inward. When you need to attach the drawer itself, just flip it outward. Another plus is the built-in level. With it, you will immediately see if your cabinet is installed unevenly. This will help you avoid problems in the future. There are 8 rubber pads on each side of the conductor. Not only do they reduce slipping, but they also protect the cabinet surface from scratches. The Milescraft 1341 Drawer Jig is a true helper for anyone who wants to install drawers quickly, easily and professionally.
