A must have kit for any level or carpenter! The Swanson Speed Square was first developed by company founder Albert Swanson in 1925. This innovative tool combines 5 tools into 1: 1.  Try Square,  2.  Miter Square,  3.  saw guide, 4.  line scriber,  & 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. Also include in the Swanson take on the classic Carpenter Pencil features bold graphite encased in durable wood, coated with high-visibility orange paint. With the flat design, your pencil never rolls away. In addition this kit includes the Swanson Savage Grip line tape measure. If you're looking for the kind of tape that latches and stays on with a Savage grip, then the Savage Grip Line measuring tape is your go-to for accurate measurements. The patented swiveling tip holds onto any material better than most conventional tapes and works especially well with PVC, conduit, and pipe up to 2 inches in diameter. The tape features large numbers on both sides of a 1-1/16 inch–wide blade to make reading easy. The patented magnetic tip attaches easily to a metal surface, such as an iron beam or window frame, and stays in place while you measure. Attach it to your tool belt with the convenient built-in clip.
