Keson RR112 - RoadRunner

Compact, accurate, and easy to carry—the Keson RR112 RoadRunner is your grab-and-go wheel for fast distance takes on pavement, compacted soil, gravel, and short turf. A smooth-rolling wheel and top-mounted counter make readings effortless, while the trigger reset at the handle speeds re-measures. The foldable shaft, debris scraper, and kickstand keep it tidy and ready between pulls—perfect for estimating, layout, striping, landscaping, utilities, and general construction.

Key Features

• Easy-read counter with trigger reset: Zero the counter at the handle—no bending—then read results at a glance.
• All-terrain tread + scraper/shield: Tracks confidently on pavement, gravel, and short turf while shedding debris for consistent measurements.
• Bidirectional measuring: Adds distance rolling forward; subtracts when you roll back to your start point.
• Compact fold & stow: Collapsible shaft packs small for truck cabs, gang boxes, and closets.
• Comfortable control: Ergonomic grip and stable frame reduce fatigue on long walks.
• Kickstand convenience: Park the wheel upright without setting it in dirt or wet paint.
