More Speed For Your Square

There aren’t many good ways to carry a rafter square.

You either have to wear a full set of tool bags or work it into your back pocket. Your square falls out, gets caught on things, shreds your pockets, or you spend extra time fishing it out of your tool bags.

“The worst thing is hearing the ting of my speed square bouncing off a concrete floor and landing in some ****** ******* puddle of chew spit.” -Aaron M. before using SquareMaster

We can help you keep your square close at hand while also keeping it secure. One of our customers said his square would fall out of his tool bags daily before he started using SquareMaster. Now he can easily slide it out and back in quickly without even looking.

Tom Silva introduced us all to the idea for a square holder on This Old House over 20 years ago. His original is no longer available to purchase so we re-booted his classic design with a few special innovations of our own.


Clip-On To Your Belt, Bags, Or Pockets

Easily clip your square on your belt or take it off quickly to fit the needs of your task at hand. Clip it to either side for left or right-hand use.


Your Square Stays Secure

No more dropping your square. A passive retention hook keeps your square from falling out and rattling around.



Works With a Wide Range of Squares 

New V3 SquareMaster fits squares with up to 1.3-inch tang. Holds squares up to 7 inches in length.
