Kreg Joinery, project assembly, general clamping, and more can all be done with Wood Project Clamps. These flexible clamps have big clamp faces that equally distribute clamping force and won't mar delicate surfaces. Wood Project Clamps automatically adjust to fit material thickness with a quick squeeze of the handles, thanks to Automaxx® auto-adjust technology — whether the material is dense, thin, or in between. Without readjusting the clamp, you can clamp a 2x4 and then a piece of 1/2" plywood. Works with the Kreg Pocket-Hole Jig, R3's, the Kreg Pocket-Hole Jig Portable Base, and the Kreg Pocket-Hole Jig Clamp Pad Adapter.
