The Squi.Jig Fusion Mini Pro Square is a 4.5 in CNC-machined aluminum rafter square for trim work, small enough to ride in a pocket. It comes in Green or Blue.
It has a 360 degree level vial you can see from any angle, a ruler on the heel to save time on trim, a quick-mark inner design, crisp laser marks and heel offsets for trim layout. Scribe notches hold your pencil in place. It's made from aircraft-grade aluminum and CNC machined in the USA.
Sven founded Squi.Jig in 2017 on a simple rule: if a tool is needed and doesn't exist, build it.
