To develop one of the world's best rafter squares, Johnson first had to engineer the EZ-Readâ¢ 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-Readâ¢ finish also increases friction to better secure your square against your lumber when using it as a saw guide. The Johnny SquareÂ® is highly durable and accurate. Its solid aluminium 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 3-1/2" and 5-1/2" as well as handy markers that measure 2x4 board dimensions of 1-1/2", 3" and 3-1/2".
This 7" Johnny SquareÂ® 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 SquareÂ® 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.
