ABSTRACT:
A right angle clamp assembly holds two frame elements in a common plane and in angled abutment to form a mitered joint. Pneumatic cylinders are arranged to move the movable clamps of the right angle clamp assembly. A fastener tool has its discharge opening positioned on one side of the location where the mitered joint is to be formed, and a brace is positioned on the other side, with the brace being movable toward and away from the location of the mitered joint. The fastener tool is tiltable with respect to the right angle clamp assembly, and control means are provided for firing the fastener tool in response to the frame elements being gripped by the right angle clamp assembly. The fastener is inserted into the mitered joint at an angle formed by the frame elements to draw the mitered joint together.
