The CST/BERGER RT104 is a mechanical measuring wheel designed for field measurement of distances up to 10,000 feet. The wheel records distance in inches and delivers an accuracy of 1 inch per 100 inches, making it a reliable tool for layout work, site surveys, and utility runs. The overall length of 36.5 inches puts the handle at a comfortable working height for most users. A built-in counter tracks cumulative distance and resets for repeat measurements. Licensed contractors, surveyors, and field technicians use this tool to measure pipe runs, conduit paths, cable pulls, and property boundaries without the limitations of a tape measure.
The RT104 suits outdoor and indoor distance measurement tasks common to plumbing, electrical, HVAC duct layout, and general construction. It performs well on paved surfaces, compacted soil, and flat concrete slabs. The inches-based counter readout matches trade workflows where measurements feed directly into material takeoffs and permit drawings. This wheel is packaged and sold as a single unit, making it a practical addition to a service van or field kit.
Designed as a general-purpose field measuring wheel suitable for paved, graded, and flat indoor surfaces used in construction and trade service work.
No installation is required. Before use, reset the counter to zero and verify the wheel spins freely without wobble. Walk at a steady pace and keep the wheel in consistent contact with the surface to maintain accuracy. Store the wheel upright or hang it to prevent wheel deformation over time.
