As a saw guide, stair layout tool or rafter tool, Johnson’s 12″ rafter square will help you get the job done accurately and easily. Its solid aluminum body construction with CNC machined edges provide greater accuracy and durability, while the low-glare, protective powder-coated finish makes the permanent graduations and numbers easy to read. This square also features scribe notches starting at 1-3/4″ that are useful when transferring outside increments from the pivot point, and handy markers that measure 2×4 board dimensions of 1-1/2″, 3″ and 3-1/2″.Solid aluminum body with CNC machined edges for greater accuracy and durabilityPermanent graduations and numbers are easy-to-readScribe notches starting at 1-3/4 in. transfer outside increments from pivot pointLow-glare, protective powder coated finishThick edge is useful as a saw guide2x4 board dimension markers for measuring 1-1/2 in., 3 in. and 3-1/2 in.Comes with instruction manual including rafter tables
