The smooth, square, straight edges on the CRL Exact Aluminum Rule are extremely accurate. Made of two inch (50.8 millimeter) wide, flexible aluminum, the rule is bend resistant and easily lies flat. The numbers are large and easy to read from either end. It has distinct calibrations in 8ths of an inch on one edge, and 16ths of an inch on the other.
