Johnson RAS-70B-ORAN 7″ Structo-Cast Rafter Square

This 7″ rafter square is a versatile tool for builders and contractors. Its thick edge is useful as a saw guide – it can be used directly with the saw against the square for cross cuts or angled cuts using the etched protractor scale. The rafter square also simplifies stair layout – its integrated distance and angle scales let you quickly and accurately mark your cut lines on your stringers.
