Kreg Bench Clamp Base makes it possible to use the power and convenience of Kreg® Bench Clamps on any work surface, creating a versatile clamping station almost anywhere. This base is an i companion to the Kreg Mobile Project Center and works with any work surface equipped with 3/4" or 20mm bench dog holes. You can also drill a hole in any work surface to easily attach the Bench Clamp Base, which can be quickly removed or relocated as needed. Installation is tool- and takes just seconds: simply slip the anchor bolt through the hole and tighten the locking knob. Then slide a Kreg Bench Clamp into the base, and you’re ready to work. The Bench Clamp Base is designed for quick setup and storage, so it’s available when you need it and out of the way when you don’t.
