The mitre square helps you to easily identify the angle of an inner corner. Never adjust the square with the indicator flag as it might damage the tool. The mitre square can also be used for identifying the angle of wind disc. You get the angle of the two pieces by reading the indicator flag.
The square is ideal for cutting ceiling mouldings, both profiled and plain, even in sloped ceilings. It can also be used when calculating the angle of skirting boards in a corner. When cutting the material, just place it against the indicator flag. To mark the cutting angle of a piece of wood, turn the square upside down and place the indicator flag against the piece.
