Wood Project Clamps are perfect for Kreg Joinery, project assembly, general clamping, and more. Available in two sizes — 3" reach and 6" reach — these versatile 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 and the Kreg Pocket-Hole Jig Portable Base.
