This set of four grooved blocks holds two pairs of K Body clamps for gluing up rectangular frame assemblies. Rest your glued-up frame on the corner blocks, slide the jaws of all four clamps up against the work and tighten. Tighten or loosen clamp screws in opposite corners to bring the frame into perfect square. KP Blocks can be screwed directly to a bench or board for production assembly.

Purchase as a set of four blocks, or take advantage of our package deal which bundles the set of 4 blocks with two 24" & two 40" K Body Clamps (catalog #KPS).
