Tightening Rockler's new Auto-Lock T-Track Clamp is literally an open-and-shut case—just slide the clamp face up to your work and close the lever! Once set, the clamping pressure is always the same regardless of workpiece size, and is adjusted only if needed with the set screw. Since the clamps apply pressure from the side, the top of your workpiece is unobstructed for easy machining and sanding. The bottom-mounted pins slide inside the miter track for stability, and can be shifted for 45° angle clamping—ideal for miters and irregularly shaped objects. When used with our T-Track Table, the clamp arm can be adjusted in and out a full 3-1/2'', allowing you to easily clamp items that lie in between the T-tracks.
