UNIPEC 7" Aluminum Rafter Square with Triangle Ruler, Protractor & Pencils

Laser-etched imperial and metric markings make this 7-inch aluminum rafter square easy to read while laying out measurements and cuts.

Its triangle ruler, protractor, and layout-square functions bring several common measuring tasks into one tool for carpentry and woodworking.

Two carpenter pencils are included for marking wood as you work, making it easier to move from measuring to marking without reaching for a separate pencil.

The essentials

The UNIPEC rafter square is made from aluminum alloy and has a classic design in red. Its 7-inch graduation range supports compact layout tasks, while the 7-inch-by-7-inch dimensions give you the square’s overall footprint. Laser-etched markings use both imperial and metric units, so you can read measurements in the format that suits your project.

This tool combines a triangle ruler, protractor, and layout square. Use it to mark angles, check layout lines, or guide a saw during a cut. For framing work, it can help with marking boards and planning angles, for woodworking, it brings measurement and marking tasks together at the bench. Two carpenter pencils come with the square for marking on wood.

Quick sizing guide

The 7-inch graduation range makes this a compact rafter square for everyday layout measurements and marking work. Its listed dimensions are 7 inches long by 7 inches wide. The dual-unit markings are useful when a project calls for imperial or metric readings, and the triangular shape supports both straight layout work and angle-related tasks.

If you are choosing between a single-purpose ruler and a multi-function layout tool, this square combines ruler, protractor, and square functions in one format. That approach is useful when a project moves between measuring, setting an angle, and marking a cut. For a typical framing task, you can use the square to lay out a line on a board, mark the cut, and position it as a saw guide.

Getting the most from it

Set the square against the workpiece when laying out a line, and use its protractor function when marking an angle. The integrated layout-square form also supports marking and guiding cuts. Its etched scale is designed to remain readable through regular handling, while the aluminum-alloy construction provides a durable metal body for carpentry and woodworking tasks.

The included carpenter pencils give you a marking tool alongside the square. Keep them together for a straightforward measuring-and-marking setup at the workbench or on a framing job. Buyers describe the square as useful and a welcome addition to a tool bag, and some highlight its perceived quality and value. These impressions reflect customer opinions rather than measured performance.

When it makes sense

Worth considering if your work includes framing, woodworking, stair layout, or other construction tasks that call for measuring and marking angles. The combined ruler, protractor, and layout-square design is especially practical when you want one compact tool for several stages of layout instead of separate tools for each task. Its 7-inch scale and included pencils make it a purposeful addition to a carpenter’s or DIYer’s kit for marking wood and guiding cuts.
