A patented square with a blade that can be rotated to 45°, 90° and 135°.

It can also be rotated 270 degrees allowing you to use the opposite side of the stock where there is no slit that for example thin sheet metal parts can slide into.

In addition, there are markings for 22.5°, 67.5° and 75°/15°. 

The square is also completely foldable, which makes it easy to store and carry in the pocket of your work trousers.

The blade is 45 mm wide to accommodate work with standard stud dimensions and has a center line that makes it easy to quickly mark out both sides of a stud.

The blade also has scribing notches, spaced 5 mm apart, which can be used to draw or cut a line parallel along an edge. 

The square has a sharp outer corner, which other adjustable squares do not have. If you rotate the blade 270° you get a rounded corner instead so you can work in uneven corners.

A robust joint and a blade of 1 mm thick, high-strength stainless steel provides a very durable design that can withstand tough working environments and will last a long time.

Carefully selected materials and manufacturing techniques such as a CNC-milled stock and a blade cut with a precision laser provide high accuracy; angle tolerance ±0.06° (±1 mm/m).
