Adjustable Triangles: "12""
Made of clear, warp-resistant acrylic for easy viewing, this adjustable triangle is accurately divided into increments of 1/2¡ from 0¡ to 90¡ and has beveled edges. The protractor scale provides additional slope and rise, and features a magnifier for precise, easy-to-read settings. It also has a thumbscrew that locks the angle securely in place.
