TDP719 - 7-Inch Aluminum Speed Layout Square

Versatile 7-Inch Aluminum Square for Fabrication and Framing

Achieve precise layouts and accurate cuts with the 7" Aluminum Rafter Angle Square (SKU: TDP719). This multi-functional tool is a staple in the arsenal of carpenters, roofers, and metal fabricators alike. Engineered from robust cast aluminum, it offers the perfect balance of lightweight portability and heavy-duty strength. Unlike steel squares that may rust over time or plastic versions that can crack under stress, this aluminum square provides a long-lasting solution for demanding workshop and field conditions.

One of the standout features of this square is its versatility. It functions simultaneously as a try square, miter square, protractor, line scriber, and saw guide. The heavy lip on one edge allows the tool to brace firmly against the workpiece, ensuring that your perpendicular lines are perfectly straight and your angles are true. This lip also makes it an ideal guide for circular saws or handheld cutting tools, allowing users to make straight cross-cuts safely and efficiently. For metalworkers, this edge is perfect for aligning against steel tubing or plate to scribe cut lines before machining or welding.

Readability is key when working in fast-paced environments. The TDP719 addresses this with permanent, cast-in graduations that stand out clearly against the tool's surface. The markings include a full 0-90 degree scale for measuring angles, as well as specialized scales for determining rafter lengths for common, hip, and valley cuts. Because the numbers are molded into the metal, they are impervious to abrasion, oil, and grease, ensuring you can always read your measurements even after years of heavy use.

The 7-inch size is the industry standard for a reason; it is large enough to handle most framing lumber and standard metal stock sizes while being compact enough to carry comfortably. The integrated pivot point allows for fast and easy triangulation of angles, streamlining complex layout tasks. Whether you are building a roof truss or fabricating a custom metal frame, this aluminum rafter square provides the accuracy and reliability needed to get the job done right the first time.
