Our 400 x 600 mm aluminum carpenter's square is tougher than steel and is the most versatile carpenter's square available. It features a 50% thicker frame to provide superior strength to competing steel squares.

The 25 to 330 mm scribing notches allow you to easily and accurately measure and rip boards. The high-visibility laser markings allow you to easily read measurements on the square. The angle marking guides allow you to set common pipe angles.
