Key Features
Overview
The SquiJig Fusion Pro 7.5-in. Rafter Square w/ 3/16-in. Heel, Green (model FP75Green316) is a 7.5-in. aluminum rafter square with a green anodized square with a black 3/16-in. x 1-in. heel. This is a rafter square designed for framing layout, rafter and stair marking, and square crosscuts with a circular saw, with a heel built for deck board spacing.
The 3/16-in. x 1-in. heel is the reason to pick this version. It sets precise deck board spacing, so you can square, mark, and gap boards with the same tool. That makes decking layout and installation faster and more consistent.
Built-in blade wrenches in 1/2 in. (13mm) and 9/16 in. (14mm) sit right on the heel. SquiJig holds the patent on this wrench-on-the-heel design, so you will not find it on other rafter squares. Scribe notches hold your pencil in place for clean, controlled lines.
The square is CNC machined from aircraft-grade aluminum with crisp, easy-to-read laser marks, and it weighs 8.0 oz. The heel bolts on and can be replaced if it is ever damaged.
It is built for framers, roofers, deck builders, and remodelers who want one square that marks, guides the saw, and handles the small jobs around it. It is 100% made in the USA.
Decking Spacer Built In

The 3/16-in. x 1-in. heel drops between deck boards to set a consistent gap, so layout and spacing happen with the same tool.
- 3/16-in. x 1-in. heel for deck board spacing
- Faster, more consistent installs
Built-In Blade Wrenches

The patented wrench on the heel adds 1/2-in. (13mm) and 9/16-in. (14mm) wrenches, so a blade change does not mean digging for a separate wrench.
- 1/2-in. (13mm) and 9/16-in. (14mm) wrenches
- Patented wrench-on-the-heel design
Saw Guide for Square Crosscuts

Hold the heel against the board edge and run the saw along the square for clean, square crosscuts on framing lumber.
- Ruler heel trims time on layout
- Scribe notches hold your pencil in place
