Designed for gluing guitar bridges, these clamps have a deep U-shape that lets them reach through the soundhole to clamp the bridge in place (combined with user-made cauls to distribute clamping force).

Strong but lightweight, they are made from cast aluminum; each has a steel spindle with a swivelling brass pad. Unlike cam clamps, they won't shift position when tightened.

Available with a 6 1/4" or 8" throat depth, with a maximum capacity of 1 13/16" or 2" respectively.
