Title: great for square corners
Review: I love it. Used it (like other reviewers) for picture frame making. It works great, makes perfect square angles, and the quick release is a great feature. Not a bad price at all for what it does. I was surprised that the threaded screw clamps are plastic, not metal, but I haven't had any durability problems with it at all yet. Holds tight, sturdy, secure and fast. I never had one of these before, and they are perfect and a must-have for 90-degree angle joining.
