The GV Mitre Square gives an automatic right angle when mitre cutting without having to estimate.
When the square is turned steplessly to the required angle, the indicator flag halves the angle. The square is manufactured in fibreglass reinforced nylon with an indicator flag of zinc-plated metal and gives an automatic right angle when mitre cutting. Can be used for both internal and external angles.
