- Made in the USA: Swanson Tool Company makes the Speed Square in the United States.
- CNC Machined: Every Speed Square is CNC machined to a perfect 45° and 90° corner. Square marks that read true right off the pivot, cut after cut, year after year.
- Heavy-Gauge Die-Cast Aluminum Alloy: A heavy-gauge aluminum alloy die-cast body, 15 times stronger than standard aluminum construction. Holds its 90° tolerance under drops, dust, and jobsite abuse.
- Matte Finish: Glare-free reading in direct sunlight. The body doesn't blind you on a roof deck at midday like a polished square will.
- 7/8 in. Heel and 1/4 in. Scribe Bar: The 7/8 in. heel holds the square against the board edge for square and 45° marks or to guide a circular saw. The 1/4 in. scribe bar rips parallel layouts off that same edge.
- Original 5 Tools In One: The original five-tools-in-one layout square: try square, miter square, saw guide, line scriber, and protractor in one heavy-gauge aluminum die-casting.
- Diamond Cutout: Look for the Diamond Cutout. That's how you know it's a true Speed Square. Marks a one-motion seat cut on common, hip, and valley rafters.
- Includes the Blue Book: Swanson's pocket reference for roof pitch, rafter length, stair stringers, and field measurements ships with the tool.
