The Swanson Speed Square first made by Swanson’s founder in 1925. This innovative tool is not only a rafter square or carpenter square, but it also combines 5 tools into 1: a try square, a miter square, a protractor, a line scriber, and a saw guide. Our Speed Square is constructed of durable heavy-gauge aluminum alloy guaranteed to last. Black-filled gradations stand out against a matte finish for easy reading. Includes markings for Swanson 1-Number Method of rafter layout, and is packaged with the Swanson Blue Book of Rafter Length and Roof Construction and the Speed Clip to keep your square handy while you work. Look for the Diamond.
