The Big 12" Imperial Speed Square With Layout Bar & Instruction Booklet is actually seven tools in one. Ideal for construction, stairway layout, and large materials, it can be used as a framing square, tri square, mitre square, protractor, saw guide and, thanks to the Layout Bar, as a stair gauge as well as for determining out of square corners. Made from heavy-gauge aluminium for durability, it has black graduations for easier reading and a matt finish to prevent glare.
The Big 12" Imperial Speed Square has 1/4" spaced notches to facilitate scribing lines. Full instructions are given in the Blue Book which contains all the formulas and instructions needed for the most commonly used roof and stairway construction.
