The Knuckle T-track Clamp offers great reach and 360°adjustability. Designed for maximum rigidity, it fits most 1/4" T-Track including our Mortise Table and Multi-angle Work Holder plus the T-Track of many other manufacturers. It gets its name from the seven circular pivot points that provide a wide range of positions for the clamp's locking knob. A pair of flat, pivoting feet that are padded with molded rubber allow you to apply even, targeted pressure to lock down the work piece without marring its surface.
Installation is simple, the head of a 1/4-20 hex bolt (included) slides in the T-slot, extends up through the clamp and is secured with a knob. You can set it anywhere along the track, spin it in any direction and clamp material up to 2 thick.
