As a saw guide, stair layout tool or rafter tool, Johnson's rafter square will help you get the job done accurately and easily. Its solid aluminum body construction with CNC machined edges provides greater accuracy along with durable chip-resistant coating. Use the scribe notches for marking and ripping lumber and handy markers that measure 2x4 board dimensions of 1-1/2", 3" and 3-1/2". This square also has deep cast-in graduations that will never peel off, wear off, fade or smudge.
Features
- Solid aluminum body with CNC machined edges for greater accuracy and durability
- Permanent graduations and numbers are easy-to-read
- Scribe notches from 1-1/2" - 9" starting at 1-3/4"
- Durable chip-resistant coating
- Thick edge is useful as a saw guide
- 2x4 board dimension markers for measuring 1-1/2", 3" and 3-1/2"
- Made in U.S.A.
How to Read a Rafter Angle Square
Find the lip edge. This edge keeps the rafter angle square from lying flat. Use it as a straight edge. Locate the hypotenuse, running at a 45°angle from the legs. Follow the lip and adjacent leg to where they form a 90°angle. This is called the pivot. Locate the common label along the long inner cutout. This measures pitch (generally used for roof pitch). Find the degrees along the hypotenuse. Use this measurement as an alternative to common.How to Use a Rafter Angle Square
Lay the square on the surface of the material so the lip extends down the long side of the material. Rotate the lip away from the edge of the material around the pivot. The corner where the hypotenuse and lip meet should move, not the pivot. Line up the desired angle, as indicated on the hypotenuse, on the same edge as the pivot. If you are measuring by pitch as opposed to angles, line up the desired pitch, as indicated by the common edge, on the same edge as the pivot. Mark along the outside edge of the rafter angle square for your angled cut.Application
This 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.
