Availability: In stock


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 2 X 4 board dimensions of 1-1/2", 3" and 3-1/2".

  • Solid aluminum body with CNC machined edges for greater accuracy and durability

  • Thick edge is useful as a saw guide

This 7" Johnny Square is a versatile tool for builders and contractors. Its thick edge is useful as a saw guide - it can be used directly with the saw against the square for cross cuts or angled cuts using the etched protractor scale. It can be used indirectly as well, using the scribing notches to create a saw cut line for rip cuts. The Johnny Square also simplifies stair layout - its integrated distance and angle scales let you quickly and accurately mark your cut lines on your stringers. And, of course, this rafter square has scales for cutting hip, valley and jack rafters.
