Milescraft 4 in. Pocket Clamp 90 deg. Pocket Hole Clamp is a versatile and fast-acting clamp designed to make your woodworking projects easier and more precise. This clamp allows you to quickly create 90-degree pocket hole joints without needing extra hands to hold parts in place. Simply slip the pin into the pocket hole joint and clamp it to the adjoining surface to keep your project square while driving screws. The metal swivel pad distributes clamping force evenly and prevents marring of your workpiece. With a clamping pressure of up to 300 pounds, a 4-inch reach, and the ability to hold materials up to 3-5/8 inches thick, this clamp is both powerful and adaptable. An integrated thumb screw lets you adjust the jaw capacity quickly, and the over-molded soft-grip handles provide a comfortable, slip-resistant grip during use. This product is imported and comes with a California Proposition 65 warning regarding chemicals that may cause cancer or reproductive harm. Model Number: 4004
