Johnson RTS24 24″ RockRipper with Structo-Cast Head & Perforated Aluminum Blade

No jobsite is too tough for Johnson’s RockRipper® drywall square. Its blade is made of extruded aluminum for maximum durability, while its molded, high impact Structo-Cast® head will stand up to the worst jobsite abuse. This drywall square was also designed to keep your work moving smoothly and easily. It features a hand grip and board guide, while the perforation on its 24″ blade helps you make fast, efficient scoring. Finally, its screened, thermal-bonded black 1/8″ and 1/16″ graduations are easy to read even in poorly-lit conditions.
