A Speed Square (rafter square, rafter angle square, triangle square) is an American, triangular-shaped, carpenters’ layout out tool which combines some of the most common functions of a try square, and framing square into one. It is used to make basic measurements and mark lines on dimensional lumber, and may be used as a saw guide for making short 45 and 90 degree cuts. Swanson is the inventor of this iconic tool!
