The Hultafors Quattro Bevel Square is an innovative adjustable square which also functions as a bevel square and an angle finder. The rotatable blade features fixed positions for 45, 90, 135 (180, 225 and 270) By rotating the blade more than 180 the opposite side of the stock where there is no slit can be used - for example, to provide a straight edge thin sheet metal cannot slide into.

There is a scale on both the blade and handle to measure angles between 0 and 90 degrees. The square is also completely foldable, which makes it easy to store and carry in the pocket. The blade is 45mm wide to accommodate work with standard stud dimensions and has a centre line making it easy to quickly mark out both sides of a stud. It also has scribing notches, spaced 5mm apart, which can be used to draw or cut a line parallel alon
