Measuring Rod Rulers
Measuring Rod Rulers ,also known as "Measuring Poles" or "Height Sticks", are very handy tools to have and come in a few styles. Some measuring poles are basically surveying rods used for elevation grade work that have a built-in dual-purpose feature which is a measuring scale on the back. Then, some of these are only built as Measuring Rulers with no grade or level rod capability and are used solely for measuring heights.
Typical uses for Measuring Poles / Rod Rulers are; Wide Load Truck Haulers that need to pass underneath bridges and overhead utility lines, Surveyors needing to know how high an overhang or bridge is. If you're wanting a Grade Rod or Level Rod, some models have the added feature of a Measuring Ruler on the back. Many times, Surveyors can reduce the need to carry a separate measuring tape if they have one of these Measuring Rulers with them. Not only can they be used in a vertical fashion, but can be used horizontally as well when, for example, when you don't have a measuring tape and need to measure the distance from the center of a manhole to back of curb.
