Our most popular Bench Klamp consists of a 3" x 4" x 1/4" thick hard-anodized aluminum insert plate and clamp. Insert plates are also sold separately that can be routed into your workbench to add multiple clamping locations. Our second version, the Large Bench Klamp, consists of a 10" x 10" x 1/4" thick steel plate that can also be used as a stand-alone clamping fixture. Both systems feature a keyed slot which allows for instant removal of the clamp from the plate.
