A T square is a tool used in drawing and engineering to guarantee a straight edge or line, at right angles.
A drywall T square is designed to act as a support and a guide when cutting plasterboard.
How is it different to other drawing squares?
Sometimes referred to as a plaster square, a drywall T square is larger than many other squares, normally at least 1220mm (48 inches) long to suit the width of a sheet of plasterboard.
A drywall T square’s length ruler (longer ruler) is double edged. This means it has measurements on both sides and either side can be used to measure from.
A drywall T square is used to accurately measure a sheet of plasterboard and to guide a knife, or similar blade, when cutting the sheet to size.
Similar to drawing squares, the drywall T square helps the user to accurately measure and mark out materials.
It can be used to give a straight line and some can even be used when measuring and marking angles.
The drywall T square’s length means that it fits perfectly to the size of a 1220mm (48 inches) wide plasterboard sheet for easy measuring and cutting.
