Available in inches or metric units, the Pocket Rod™ can be used as any tape measure. However, when pulled completely from it’s housing, it becomes a straight, metal reference scale that can be placed against a wall for reference. When set on the ground, the numbers read from ground level up. When you are done, simply retract the Pocket Rod™ tape back into its plastic housing. The Pocket Rod™ is 2 meters (6? feet) tall with black numbers on a white background on one side and red numbers on a white background on the other side.
