Keson measuring wheels are used to measure boundaries or large areas for applications in construction sites, road marking, paving, fencing and traffic control operations. These measuring tools feature a molded ABS / tubular steel frame with a plastic spoked wheel construction, which allows precise measurement of perimeters in a single go by simply changing the position of the tool. These wheels are capable of measuring distances up to 100000 feet, and to cover outdoor terrains and indoor jobs, like marking plumbing locations or measuring carpet areas, these wheels are offered in both small and large circumferential sizes (1 and 4 feet). Choose from a broad range of these Keson wheels, available in different handle lengths and weights, on Raptor Supplies.
