Knew Concepts Bench Clamp 

This Knew Concepts Bench Clamp will fit onto any surface from 3/4" to 3.7" in thickness, allowing you to fit any tool with a dovetail plate fastening wherever you need it. It is specifically designed for use with the Knew Concepts Sawing Plate (997 3308). The bench clamp features a selection of holes through which the clamp can be tightened, bringing an end to those annoying situations where beams on the underside of a table, bench or desk make it impossible to fit a bench pin. The main body of the clamp is constructed from aircraft grade aluminum, with a 2" hardened steel disk for use as an anvil plate set into the top portion of the clamp. The facing portion of the clamp is also hard anodised to avoid accidental filing, and so will not contaminate tools with aluminium if you slip while working. Clamp measures approximately 100mm wide, and includes a ruler across the front edge for fast measuring.
