Description
To develop one of the world’s premium 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 continuous scribing notches that are ideal for ripping at 1-1/2 in, 3-1/2 in and 5-1/2 in as well as handy markers that measure 2×4 board dimensions of 1-1/2 in, 3 in and 3-1/2 in.Unit: EAUPC: 049448190416Model Number: 1904-1200
