5 Tools In 1
The 250mm Metric Speed Square With Instruction Booklet is actually five tools in one. Ideal for roof construction and stairway layout, it can be used as a tri square, mitre square, protractor, line scriber and saw guide. Made from heavy-gauge aluminium for durability, it has black graduations for easier reading and a matt finish to prevent glare.
Easy To Use
The 250mm Metric Speed Square has ¼” spaced notches to facilitate scribing lines. Full instructions are given in the “Green Book” which contains complete instructions on basic roof construction, rafter tables and a section on stairway building.
