These precision-machined assembly triangles give you a rigid, repeatable reference for squaring frames, panels, and casework, so you can stop fussing with a speed square and a prayer. Each triangle is cut from 1/2" phenolic for a surface that stays flat and holds up to shop use, with multiple slots and mounting holes so it works with whatever clamps, jigs, or fixtures you already own. Line it up, clamp it down, and get back to building. Sold as a pair for two-sided support on larger assemblies 7" legs for a stable, generous reference surface Slotted for any clamp, adjust position without extra hardware Mounting holes for permanent attachment to benches, jigs, and fixtures 1/2" phenolic construction resists warping, moisture, and wear Made in the USA Use them to square up frame assemblies, hold workpieces steady during glue-ups, set up router tables, or build repeatable jigs and templates. Once a project's been squared with these, guesswork is off the table.
