|Peak C CLAMP now you can mount your Peak vise onto anything from a banquet table to a picnic table. The Peak C Clamp clamping jaws ride on 2 precision guide pins keeping the jaw faces parallel. Unlike a typical clamp screw, there is no rotating clamp pad causing your vice to "walk" as it's clamped to the table or marring the finish. The rabbeted face engages the edge of your table so your vise won't rock. As one reviewer stated "You could press bearings with this clamp." Works with any 3/8" shaft and the Clamp will also accept Peaks Accessory Post.
