The alpha square is an advanced version of the carpenter's square and an indispensible marking tool for all carpenters. You can set this tool to any additional degrees you may require between 0° and 90° and mark them or read them off on the beam.
The movable bracket with degree scale is seamlessly welded to the horizontal and vertical marking blades and is also firmly riveted to the square itself.
With careful consideration of where you place the tool along the edges of the workpiece, you can greatly reduce the time required for marking because you do not have to set any opposite angles.
