We are proud to distribute these Keson Pocket Rods to our forensic customers. While they may look like standard tape measures, in actuality each of these tools are a rigid height gauge that are designed to roll into a housing that looks like a tape measure. And though you can pull the tape out part way and use it like a roll tape, its uniqueness and functionality comes from pulling the tape completely out of its case creating a stable rule for vertical measurements.
The rule itself is nearly 1” wide and comes in two reading varieties, fractional and metric. The fractional model shows black graphics on the inner/concave side of the rule and red graphics on the other side. The red graphics are inside on the concave side with black graphics on the other side. This unit reads in centimeters with 1/10th meter labels, all the way up to 2 meters.
The ruler itself is a steel blade with a Tecron-tuff coating so that it is weather and moisture resistant. The end is a heavy-duty hook that reads at true zero. Using the rule as a height rod, the Keson Rod nearly stands up on its own. Just put a little weight on the hook, like stepping on it with your foot, and it stands up firm and true.
