A remarkably simple and effective clamping system. Long (24") threaded rods screw into four corner blocks; the whole assembly is quickly closed up to the frame by sliding the speed nuts along the rods. A quick locking twist applies final pressure. Each corner is relieved with an inside channel to ensure that the mitre fits snugly. Set includes 8 individual 24" rods, 4 extension nuts, 4 tightening nuts, and 4 corners.Click Here
