Milwaukee Electric Tool Corp E3992 Mag Rafter Square

Product Description

The Milwaukee Electric Tool Corp E3992 is a 12-inch magnum rafter square built for layout work on framing, roofing, and stair-stringer projects. The body is anodized aluminum, which resists rust and corrosion in wet or outdoor conditions. Laser-etched markings deliver permanent, high-contrast readability in low light or direct sunlight without fading or rubbing off. A thick reference edge provides a stable, controlled guide when used alongside a circular saw, reducing the risk of blade deflection during cuts.

This rafter square is suited for residential and light commercial framing, roofing layout, and deck construction. Carpenters, framers, and general contractors use it to mark rafter cuts, stair stringers, and angle layouts. Graduated notches along the body allow a pencil or scribe to pull consistent layout lines without repositioning. Stamped-in conversion tables are integrated directly into the tool body, keeping common framing references accessible at the point of work without consulting a separate reference card.

Installation Notes

This tool requires no installation. Position the square firmly against the work surface before marking or cutting. When using as a saw guide, verify the thick edge is fully seated against the material to prevent blade drift. Keep the tool clean of sawdust buildup around etched markings to maintain readability.
