The Right-Angle Clamp makes projects with 90° joints faster and easier than ever by giving you the helping hand you need to hold the parts in position as you drive in the screws. Just slip the pin on the Right-Angle Clamp into a pocket hole, close the clamp, and it draws the mating pieces tightly together. The swivelling clamp pad opposite the pin grabs the mating piece securely. Thanks to Automaxx auto-adjust technology, the Right-Angle Clamp adjusts to match the material automatically with a simple squeeze of the handles. This handy clamp works with all kinds of materials, from thin 1/2" plywood to thick 2x4 boards.
