Detailed Review
The Swanson Tool Co S0101 7-inch Speed Square is a multi-use layout tool designed for carpenters, roofers, construction workers, and home DIYers. It handles the core duties of five separate instruments, functioning as a try square, miter square, saw guide, line scriber, and protractor in a single setup.
For everyday woodworking and framing, the square provides fast 90-degree and 45-degree angle marking alongside 1/4-inch spaced scribing notches and a dedicated diamond cutout for rafter seat cuts. Black gradations printed against a matte, non-glare finish keep angle markings legible across various lighting conditions, while the rigid edge guides your saw for clean cuts.
Roofing layouts are streamlined thanks to specialized gradations for hip, valley, common, and jack rafters. To save time on the job, the included pocket-sized Swanson Blue Book supplies extensive inch-rise-per-foot-run calculation tables so you can lay out pitched roof angles without doing manual math.
Keep in mind that the tool is fixed at a 7-inch layout size, which may require repositioning on wider timber or large sheet goods. The product details also do not specify the exact metal or construction material used for the body.
Verdict: The Swanson S0101 Speed Square is an essential, multi-functional tool for anyone needing fast, dependable angle layouts and saw guiding on framing or DIY builds.
