Stanley 45-500 Steel Carpenter's Square 16 x 24 Inch

The Stanley 45-500 is a steel carpenter's square with a 16 x 24 inch L-shaped blade, the tool used to mark and check right angles and to measure out cuts. Stanley makes it from high-quality hardened steel for durability and long life, and embosses the inch graduations on both the face and the back so they stay easy to read. A reverse-reading scale makes measuring quicker, and a clear protective finish helps the square resist rust. Stanley describes it as durable and accurate for measuring and marking.
