The Omni-ruler is a series of ruler sections that can be combined to create a ruler or range band stick that is unique and customized to you. You can alternate colors to indicate each inch or use specific colors to mark important distances such as ranges. A single end cap is needed to complete the ruler. This gives you a flat surface so you don't have to worry about any exposed threads. The system collapses for easy storage and can be quickly reconfigured. The sections are aluminum and come in a variety of colors. The color is anodized onto the metal.
