This system combines the Automaxx 3 in. Bench Klamp and the Klamp Plate so you can create an incredibly strong and versatile clamping station anywhere you need 1. The Klamp Plate can be quickly routed into any wood or composite work surface such as a workbench, saw horse, table saw extension, etc. It accepts any Kreg Bench Klamp once installed. When not in use, you can remove the clamps to regain your flush work surface. The Automaxx 3 in. Bench Klamp features Auto-Adjust technology that adjusts the clamps automatically, eliminating the need to readjust the clamp for every change in material thickness. Just squeeze the padded handles and the clamp locks your material to your bench top, no matter what the thickness.

In addition to these great features, Automaxx Bench Klamps also feature extra-large clamp faces, comfortable padded handles, and heavy-duty construction. Material: Metal.
