For joining two pieces of stock at 90°, this small corner clamp holds both parts firmly while aligning them squarely to one another.

It has a single Acme-threaded steel screw, which drives floating jaws that can skew off-axis to hold parts of different thicknesses. For corner joints, it can hold two pieces of matching stock up to 2 1/4" thick, and with pieces of unequal thickness, it accommodates stock up to 2 3/4" thick.

Openings in the fixed jaw accommodate stock up to 1 3/16" thick when making T-joints, and permit access to the outside corner of the joint for setting dowels, driving fasteners or cleaning up glue squeeze-out.

The clamp has sturdy die-cast jaw bodies with a durable finish that won’t mar your work, and can be mounted on any work surface up to 2 1/4" thick with the two included table clamps.
