Johnson Level 7" Johnny Square® Aluminum Rafter Angle Square

Item #27629
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.
Product Overview

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".
