CRL PPG® Glass Running Pliers have unique "floating block" jaws that are self-aligning to keep them perpendicular to the glass at all times. This eliminates any "flares" caused by conventional pliers. Excellent for long cuts, as well as specialty cuts for mail slots, corner notches and speak tube holes. The PPG1 can be used on all thicknesses of glass from double strength to material 1/2" (12 mm) in thickness. These quality pliers for the professional glazier are made in the U.S.A. Overall length is 9-1/2" (241 mm).
