Johnny Square Die-Cast Aluminum Rafter Squares

This Johnny Square is proudly Made in the USA and is the first rafter square on the market to use a continuous scribing notch - meaning you can mark and rip lumber to any size you want. This rafter square is solid aluminum die-cast and CNC-machined right here in Wisconsin. And, staying true to its Wisconsin roots, Johnson even included an integrated bottle opener in the center of the square. This square uses deep cast-in graduations that will never peel off, wear off, fade or smudge and also comes with a low-glare, protective powder-coated finish. It also features handy markers that measure 2x4 board dimensions of 1-1/2", 3" and 3-1/2".

Pertains to models 1941-0700 and RAS-1B.

Key Features

Solid Aluminum body with CNC machined edges for greater accuracy
Permanent graduations and numbers
Continuous scribing notches - ideal for ripping at 3-1/2'' and 5-1/2''

I've gone through several speed squares over the years trying many different brands and styles. These Johnsons seem to be the best quality for the lowest price and one of the only styles that actually has scribing notches over 5.5".

I used to have the black “laser engraved” version of this square but after a year or so of use the square was fading and the measurements were hard to read. This one isn’t as cool looking but with actual engraved markings will be lasting mich longer. Love the scribe notches as well and it has a bottle opener built in.

Fantastic gauge!

Reviewed in the United States on August 31, 2018

Style: 7'' Aluminum Rafter Angle SquareVerified Purchase

I have a couple of these already but purchased this one as some are plastic and the metal one doesn't seem to be square anymore. This Johnson is everything I expected. It is square and true, the markings are all clear, consistent and legible and the casting and machining are well done. The finish is even which helps readability and hey, aesthetics can't hurt. The only disappointment is that the pocket manual this is advertised as including is not present. I've seen these manuals before and they are worth as much if not more than the square itself. I've found pdf's to print off but the value is in the size of the booklet which can be easily carried in a pocket for ease of reference. The missing manual is the ONLY thing keeping this from a 5 star review.

Great square! The extra scribe notches are very useful for marking rip cuts. The imprinted markings and numbers ensure that the square never becomes unreadable. I prefer this square over the other Johnson Johnny square that is matte black with laser etchings. The finish and etchings eventually become so scratched that they are unreadable.

Love the notches for marking rip cuts, that was the main reason for my purchase. Don't know why all brands don't have this useful feature. Tool is well made, arrived with a couple of small areas where the paint/coating was chipped, but it's gonna get scratched up in use anyway so not a big deal.
