Description

To develop one of the world's best rafter squares, Johnson first had to engineer the EZ-Read™ finish, its revolutionary anti-glare protective coating that diffracts sunlight rather than reflecting it, so it looks as crisp in full sun as it does in the shade. The EZ-Read™ finish also increases friction to better secure your square against your lumber when using it as a saw guide. The Johnny Square® is highly durable and accurate. Its solid aluminum body construction with CNC machined edges ensure an accurate reading every time. This rafter square also features strong magnets for hands-free use as well as continuous scribing notches that are ideal for ripping at 3-1/2" and 5-1/2" as well as handy markers that measure 2x4 board dimensions of 1-1/2", 3" and 3-1/2".

  • Fantastic square.
Size: 7-1/4-inch Style: MACH-1 with Level Vial
Fantastic speed square. Has all the marked measurements needed and the built in level is handy to have. This square is built right and heavy duty. Highly recommended if you’re a carpenter looking for a new one.

  • Well made
Size: 7-1/4-inch Style: MACH-1 with Level Vial
Well made, easy to read. I'm not using the bubble level near as much as I thought I would, but still handy for simple checks.

It's everything a speed square can be. It will not fit into the holstery speed square holster because the foot is too thicc because of the bubble. The bubble is replaceable but good luck finding one. There are a few Johnson brand ones here in the way way back of Amazon, if you can make it down the rabbit hole, but the sizes are inconveniently advertised as fractions that don't quite translate to 16ths of an inch. You would have to remove the bubble and then use a caliper, which I don't have. I'm worried about it being stolen at work because there's nowhere on the damn thing I can paint pen my name on it. It's almost too many functions and I'm probably never going to use them all. ... show more

  • Clearly one of the best small squares out there
Size: 4.5-inch Style: Standard
Super handy size of this square makes it a must have around the wood shop. Love the white on black easy-read markings. The price is right and it seems to be a quality tool. Was going to pay the price for one of those fancy smaller squares, but glad I didn't. For what I would have paid, I could have three of these. Will definitely get another one to have as a spare. ... show more
