Bessey Single-Spindle Edge Clamp

This clamp is designed to interlock with the rail of a bar clamp, letting you apply force to the edge of a workpiece while making use of the clamps you already have.

A thumbscrew lets you securely attach the single-spindle clamp to a rail up to 1/2" thick. The pivoting face of the spindle has a removable plastic pad to prevent marring of the wood surface.
