Rockler Adjustable Clamp-It® Assembly Square

Jigs and clamping devices are great for holding pieces of a project while they are nailed or screwed, this is often difficult or impossible to do well without assistance.
The Adjustable Clamp-It rotates from 45 to 315 and is indexed at 5 increments providing lock in registration at most commonly used angles. Simply set it to the desired angle, loosely position it, fit the clamps and tighten once happy with the positioning.
Manufactured from high-impact rigid polycarbonate, it is both tough and accuracy. Turn the winged knob to tighten and loosen, while interlocking teeth securely set angle.
