The Swanson Speed Square was first developed by company founder Albert Swanson in 1925. This innovative tool combines 5 tools into 1. Try Square, Miter Square, saw guide, line scriber and 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 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 Swanson quality.

Exactly what it should be. With any tool, you get what you pay for, but this square provides excellent value for its price.The protective finish on the aluminum is not slippery or glossy. The markings are extremely legible, with good contrast against the rest of the body, and all the markings are inset before being coloured black so they will never wipe or scratch off.It has about twice the features as most squares but doesn't cost enough to cry about when you tear it up scraping concrete or something with it.

Used for layout when framing and carry it in my rig at all times as my everyday square. Easy to read. Nice finish. Accurate. The latest updates have made it more useful. Be sure to watch videos online about all the features. It got a 4/5 on value because everything gets a 4/5 for value. Things are too expensive - across the board.The most versatile rafting square I've ever used.Mitch- Contractor/Remodeler, 15 yrs

Great tool, heavy duty, a little heavier then expected, easy to read markings, great little booklet came with it for someone who's new to a speed square, price is a bit high, shipping was reasonable.
