It combines a rule with a movable head for marking and checking right angles and short measurements. Check that the head locks firmly before transferring a line.
Check Right Angles and Transfer Cut Lines
A small error in the first marked angle can carry through every piece cut from it. MacBlair stocks squares for checking and transferring layout lines, including a Stanley 300mm diecast combination square, 1200mm folding square, adjustable quick square, dual-colour squares in 180mm and 300mm sizes, and a Tala 225mm try square. The range also lists a rosewood bevel for transferring an existing angle.
Choose a compact square for work at a bench or on a board, and a larger folding format when marking across wider sheet material. A combination square can check a right angle and use its rule for short measurements. An adjustable quick square suits repeatable marks where its settings match the job. Before a batch of cuts, check the square against a reliable straight edge.
Mark out with site pencils and markers, then confirm dimensions with rules and straight edges. Browse the parent measuring and marking range, or find hand saws for cutting to the line.
Squares FAQs
A larger folding square can help set out a right angle across wider materials or site layouts. Fold it for transport and check that it opens fully before use.
A try square is used to check or mark a fixed right angle. A bevel is adjusted to copy and transfer another angle rather than provide a fixed 90-degree reference.
Mark a line against a straight edge, flip the square over and compare a second line from the same point. If the lines diverge, check the square before relying on it for repeated cuts.
A compact try, combination or quick square can be easier to position on a small board. Choose a size that sits securely against the reference edge.
