Mayes 12 in. L X 1 in. H Plastic Angle Square

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.
