Alumicolor has a full line of Professional T-Squares with a 2" wide extruded aluminum blade. Calibrations are made using Alumicolor's photo anodizing process giving all our products a smooth, tick-free finish that will not wear.

The black ABS plastic heads are lightweight and virtually unbreakable. The heads are secured with 5 screws instead of rivets. Unlike the Standard T-Square, the Professional aluminum blades have channeled backs that glide easily on drafting tables.
