Granite Straight Edges, Parallels & Tri-Squares
Available4 products
Granite straight edges, parallels, and tri-squares are solid tools used for layout and positioning. Granite straight edges are non-graduated tools that have a single long and narrow face with a flat finish. They are generally 2 or 3 inches wide and often have smooth holes for lifting. Granite parallels are used to set up work on surface plates and machine tables. They are also used to elevate work above the surface of a plate for quick and easy inspection. Granite tri-squares have three finished sides and are used to check for 90° squareness. These granite tools are durable, corrosion-resistant, and tolerate temperature fluctuations and resist thermal expansion.
