DEWALT Grampo de Esquadria 90° DWHT83840-0

For woodworkers and cabinet makers who need perfect right-angle joints, the DEWALT DWHT83840-0 corner clamp holds two workpieces at a fixed 90° angle, leaving both hands free for fastening. The die-cast aluminum body keeps it light enough to reposition quickly, while the steel jaws and screw deliver firm, non-slip clamping pressure.
