Alumicolor™ triangular Drafting Scales are made of extruded aluminum. Alumicolor's™ photo anodizing process makes the calibrations a part of the aluminum, providing a smooth, tick-free finish and markings which are resistant to cleaners and solvents. Hollow Scales are lightweight for easy portability.

L2R™ Architect Scales were developed with calibrations that read from left to right only. This makes it easier to read than traditional architect scales, which read from left to right and right to left.

This scale offers the following graduations: 1/32, 1/16, 1/8, 1/4, 1/2, 16 to the foot.
