Rockler's Clamp-It Assembly Square offers the solution to clamping, gluing and assembling components square. It can be used on its own, or with the Rockler’s Clamp-It Corner Clamping Jig, or even Rockler’s Universal Fence Clamps.
Simply clamp one piece to one arm of the Square, and then another piece to the other arm, make any adjustments to make them flush with each other and fix in whatever manner is planned. It works with any type of square joinery, from nails, glue, dovetails, rebated joinery, and more.
The oversize dimensions make this sturdy enough to cope with most jobs thrown its way, 200mm x 200mm x 38mm.
