Contoured hardwood handle works like a straight edge and slides smoothly along the drywall as the two scoring wheels cut or perforate both sides at once. Wing nut adjustable guide is rigid steel and adjusts to a maximum of 5 inches or 12 centimeters. Scale is stamped into the guide and marked in 1/4-inch and 1-centimeter increments.
