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''
