Mayes 20012 Polystyrene Angle Square (12 Inch) with Level Vial

The 12 Inch Polystyrene Angle Square (with Level Vial) by Mayes is a multi-purpose tool for measuring, cutting and leveling. It quickly finds angles and pitches, squares up lumber, and includes a high visibility vial to check for level. With a high impact composite polymer frame, it is tough but lightweight. Permanently impressed scales will never fade (and are accurate to 0.001 inch).
