Johnson Levels RAS-1B 7 In. Aluminum Rafter Angle Square

Solid aluminum cast body with exclusive CNC (computerized, numerically controlled) machined edges. Permanent molded graduations. Low-glare, protective powder coat finish. For general carpentry use, this square is versatile and unbreakable. A more compact version of the standard 12 In. square (great for when you’re up on a ladder), this tool gives you both 45- and 90-degree angles. It can also be used as a ruler, and can be used to measure other angles. The diagonal edge has markings for laying out rafters, roof trim and stair angles.
