On the job · Phoenix, AZ
The standard Albert Swanson set in 1925 hasn’t changed. Now made with high-grade die-cast aluminum. Unlike various rafter squares, the Speed® Square is embedded with deep black markings and a matte finish that reads true in direct sunlight. Accuracy at every edge, every year since.
The Reference Standard for Layout
Rafter tables, roof pitches, stair geometry. A century of layout math, indexed, searchable, and free on every device.
