Wood Project Clamps are perfect for Kreg Joinery, project assembly, general clamping, and more. Available in two sizes (6" reach and 3" reach) these versatile wood clamps have large clamp faces that distribute clamping force evenly and won't mar delicate surfaces. They are compatible with the Kreg Pocket-Hole Jig R3's Clamp Pad Adapter, 300-Series Pocket-Hole Jigs and with the Kreg Pocket-Hole Portable Base. Thanks to Automaxx Auto-Adjust Technology, Wood Project Clamps adjust to match material thickness automatically with a simple squeeze of handles - whether the material is thick, thin, or in between. You can clamp a 2x4 and then a piece of 1/2" plywood without ever readjusting the wood clamp.
