If you’re talking layout tools on the job — then the is that little square that punches above its weight. It’s a compact 177 mm (7″) square built to take daily use and give you repeatable, accurate lines whether you’re cutting rafters or checking squareness on a stud wall.

This isn’t some backyard DIY toy — the premium rafter measuring square is stamped with clear gradations and angle scales that help you lay out cuts in degrees, mark jack, hip and valley lines, and snap accurate reference points fast. You’ll find it keeps up with rough carpentry and fine finish work alike.

Key Features:

• Stamped Graduations - Makes reading measurements fast and clear, even in low light.
• 90° & Angle Scales - Lets you mark out square and angle cuts without flipping between tools.
• Top Cut Scales - Built-in guides for common jack, hip and valley rafters save time on layout.
• Scribe Notches - A quick way to notch and mark rip cuts ensures cleaner lines.
• Fixed Large Base - Gives a solid bearing on stock so your layout doesn’t slide around.

Applications

This tool shines in framing and roofing work where accurate angles matter — the premium rafter square is ideal for marking rafters, laying out stairs, verifying squareness on frames, and even as a saw guide on crosscuts. You can go from rough framing to detailed carpentry without swapping tools.

Why Choose This Model

Here’s the thing — not all small squares are created equal. The DeWalt 177 mm rafter measuring square gives you etched, high-contrast markings that last, a stiff aluminium body that won’t twist under pressure, and a size that’s easy to carry but still grips lumber well. On site, that means fewer guesses and more confidence in your layouts.
