SQUARES

Speed® Square

S0101

This is the one and only Speed® Square, invented by our founder in 1925. This unique tool is actually five tools in one: a tri-square, a miter square, a protractor, a line scriber, and a saw guide. The Speed® Square is constructed of durable heavy-gauge aluminum alloy. Includes markings for Swanson's® One-Number Method™ of rafter layout, and is packaged with the Swanson® Blue Book of Rafter Length and Roof Construction. Look for the Diamond®.
