T Track Hold Down Clamps are the perfect T Track Accessory: Rockler's new auto-lock T track clamp is literally an open-and-shut case. Just press down the lever to secure anything from veneer sheets to lumber up to 2-3/4'' thick! Makes Your Work Easy: Our T track clamp hold down automatically adjusts for thicknesses from 0'' to 2-3/4'' securing your work is as fast and as easy as flipping a switch! Minimize Obstructions: Once set, the clamping pressure is always the same regardless of workpiece size, and these T track clamps are adjusted only if needed with the set screw. The clamps pivot 360°, allowing you to clamp near the workpiece edge to minimize obstructions. Easy To Install: A large knurled wheel locks the clamp securely to the T-track. The toggle foot is adjusted with the knurled aluminum knob for best placement—no wrenches required. While the clamping foot pivots on a ball joint so it can adapt to any angle and is rubber coated to prevent marring. Durable Construction: These woodworking clamps are made from durable, heavy-duty metal construction which gives longer life. Our woodworking tools and accessories are perfect for your workshops.
