Rockler’s Clamp-It Assembly Squares

For years, Rockler’s innovative Clamp-It Assembly Squares have been a woodworker’s best friend in difficult assembly projects. Simply put, the Clamp-It is a square that you can clamp. The original Clamp-It holds awkward materials securely in place during assembly, and guarantees a 90 degree joint every time. It replaces custom clamping jigs, and eliminates the need for clumsy, heavy bar clamps.
