Everything You Love In A Speed Square - And MORE!

Introducing biggest evolution of the Swanson Speed Square in almost 100 years!

The Speed Square PRO.

This revolutionary layout tool born out of the true legacy tool, the Speed Square, is packed full of new features and has the same reliable features you have always counted on from the Swanson Speed Square making layouts even faster and easier!

The Speed Square PRO starts with all the incredible features of the original Speed Trim Square, then takes it up a notch. From a new 22½ degree angle coming off of the pivot for quick layouts to an additional 5½ inch diamond mark for working with 2×6 material.

It also has 1½ inch edge used to measure the width of 2X material for quick framing.

The Speed Square PRO is a proficient tool - builders appreciate how accurate, durable and reliable it is in their tool assortment.

And while the Speed Square PRO is designed for the true professional - anyone can use it!

Extremely handy and easy to use. It's been invaluable for a DIY project I'm working on that involves wood cutting and carpentry. This is a heavy-duty speed square. Well made and very sturdy. It's entirely precise enough for my needs and all the markings are easy to read. Also comes with an informative little book. Maybe the best $11.99 I ever spent. Made in USA!

I'm new to using speed squares (or at least it's been a few decades).I researched heavily, and this is the everyman's dependable American-made tool, per all the pros. There are better, more functional, machined options, but for my purpose of building a deck, this is fantastic!

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.

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
