We carry all types of Rods such as Grade Rods, Level Rods, Direct Elevation Rods, Sight Rods, Lenker Rods, and Specialty Smart Rods. Grade Rods, also known as Level Rods, are a necessary tool for most building contractors, paving companies, excavation companies, concrete professionals, and plumbers residential or commercial. As an added feature on some rod models, they have measuring ruler capabilities, where you can extend the rod up to the underside of a bridge or ceiling and then read the height at eye-level. Also be aware that some rods have their measuring faces made for when using laser levels as opposed to an optical level. Keep in mind that a fiberglass grade rod will last much longer than an aluminum grade rod, given that both types are cared for (nothing can last if you run over it with a truck or heavy equipment).
