Swanson Swanson S0101 Speed Square Pro 7-1/2 In. Aluminum Layout Tool With Blue Book

The Swanson Speed Square Pro is a versatile aluminum layout tool that serves as a try square, miter square, saw guide, line scriber, and protractor. Developed by company founder Albert Swanson in 1925, this die-cast tool has become the most trusted square of its kind for professionals and DIY enthusiasts alike. Whether you're framing, roofing, or working on general carpentry projects, the Speed Square Pro delivers the precision needed for accurate measurements and cuts.

This layout tool solves the challenge of marking angles and making square cuts quickly and accurately. The Speed Square Pro features a diamond cut-out bridge that adds structural support, along with the iconic Swanson Diamond Cut Out at the 3-inch mark. Beveled edges allow the square to get closer to your working material for more precise top-cut measurements. The matte finish with black-filled gradations makes measurements easy to read, while the heavy-gauge aerospace aluminum alloy construction is built to last.
