Mark accurate 45° and 90° lines with the Empire 300mm Metric Aluminium Rafter Square. It’s also suitable for measuring vertical and horizontal surfaces to check if they’re plumb or flush. Use its large heel and rational size as a saw guide for crosscutting boards up to 300mm wide.

This Rafter Square is constructed from solid aluminium that won’t bend or break. The markings are stamped into the material to ensure they won’t wear or rub off over time. Scribe-Guide™ notches make it simple to mark out 5mm increments.

Metric markings feature on both sides of this Rafter Square. Use the pivot point for marking angles from 0-90 degrees. Use the embossed conversion table for making quick rafter calculations.
