Miter Square, 3. saw guide, 4. line scriber, and 5. protractor. The Speed Square is die-cast for durability and accuracy. Made of heavy-gauge aerospace aluminum alloy, it is built to last. Black-filled gradations stand out against a matte finish for easy reading. The Speed Square includes the Swanson Blue Book of rafter length and roof construction and also features markings for using the Swanson one-number method of rafter layout. The Swanson Speed Square is our most popular product and remains the most trusted square of its kind. Look for the Diamond cutout for genuine Swanson products. From the Manufacturer The Swanson Tool SO101 7-inch Speed Square is a popular pocket-sized square that incorporates features of the framing square, tri, miter, and protractor squares. Common rafter and hip/valley rafter scales permit one-number references for all cuts. The square is merely rotated to the proper roof pitch value on either scale to assure the correct angle cut. The slot along the scales will accommodate an adjustable locking pin for repetitive cuts using any 1/4-inch bolt and nut. Comes with a handy, 62-page pocket sized booklet that provides vital instructions, reference diagrams, and tables for the construction of roofs and stairs.

  • Full function speed square
Style: Trim Speed Square
Exactly like it’s big brother but small enough to fit in an apron. I checked it for square and 45 degrees and it right on the money. Weighs practically nothing because of its aluminum construction and clear markings. Excellent value and perfectly square. I can stop looking for squares now since I have four different sizes up to 18”. ... show more

This Swanson 7-Inch Speed Square arrived too late, and I had already bought another one for my project. However, my friend used it and said it works really well — accurate, sturdy, and easy to use. Even though I didn’t get to try it myself, the positive feedback and the fact that others in the reviews are happy with it makes me confident enough to give it 4 stars. Seems like a solid tool overall. ... show more
