Squi.Jig 3in Framing Jigs - Blue (2 Pack)

SquiJig Framing square attachments are designed and created to hand tighten down onto a carpenters square or commonly known as a framing square, to create a jig to layout rafters, stair stringers, or common or repeated layout marks. They were designed with a taller profile verse the standard framing square attachment, to combat any wane or defects the edge of the lumber you're working with may have.
