The hultafors quattro 270 adjustable try square is a versatile marking and measuring tool designed for precision work across carpentry, joinery and metalworking applications. This innovative square features a blade that rotates to fixed angles of 45°, 90° and 135°, with additional reference markings for 22.5°, 67.5° and 75° 15°, making it ideal for complex marking tasks without requiring multiple tools. The blade can be rotated a full 270°, allowing you to use the opposite side of the stock where there is no slit, preventing thin sheet metal parts from sliding into gaps during marking. When rotated fully, the rounded corner design enables accurate work in uneven corners where standard squares cannot sit flush. The 45mm wide stainless steel blade accommodates standard stud dimensions, whilst a centre line marking allows quick marking of both sides of studs. Scribing notches spaced 5mm apart enable precise parallel lines along edges. Built to professional standards, the square features a cnc milled aluminium stock with full anodising and a 19mm thick handle for durability. The high strength stainless steel blade is precision laser cut to just 1mm thickness, achieving an impressive angle tolerance of ±0.06° ±1 mm m. The completely foldable design makes it compact enough to carry in work trouser pockets whilst maintaining the accuracy demanded by professional tradespeople.
