The Rafter Square is a robust and versatile tool for all craftsmen. It features a solid aluminum body with CNC-machined edges for greater accuracy and durability. The tool allows you to make fast and precise 45° and 90° markings. In addition, its thick edge is useful as a saw guide – it can be used directly with the saw against the square for cross cuts or angled cuts.

This highly versatile tool can be used indirectly as well, using the scribing notches to create a pencil line or for when cutting plaster with a knife. The Hultafors Rafter Square can also be used as a protractor, for easily finding and marking various common angles. The tool has scales for cutting hip, valley and jack rafters.
