PRODUCT OVERVIEW

Product Description

The SitePRO 31-RS312 is a contractor-grade measuring wheel engineered for rapid, accurate distance measurement across the demanding surfaces found on active construction sites, municipal right-of-ways, and survey corridors. Where steel tapes create operational friction and laser distance meters lose line-of-sight, the RS312 keeps crews moving. The 12.5-inch aluminum wheel paired with a precision-molded wide rubber tire maintains consistent ground contact on gravel, compacted dirt, rough concrete, and uneven asphalt — surfaces where narrower wheels sink, skip, or bind and introduce cumulative measurement error.

Built for the Jobsite, Not the Showroom

The RS312 is designed around how contractors actually measure. The 5-digit mechanical counter captures cumulative footage up to 9,999 feet 11 inches without electronics, batteries, or firmware updates. A reset button clears the counter between measurements, and the fold-flat handle collapses the wheel for storage in a truck bed, tool bag, or equipment trailer without taking up meaningful space. The sturdy powder-coated frame handles the abuse of daily field use across road construction, utility installation, landscaping layout, fencing, and commercial site prep.

Job Applications

Road and Utility Construction: Walk storm drain runs, curb lines, or conduit routes quickly without setting up tripods or managing tape reels in traffic-adjacent work zones. The RS312 covers ground fast and keeps your count accurate even on chip-seal or rough base course.

Commercial Site Layout: Establish setback distances, measure parking field dimensions, or confirm lot boundary distances during grading and paving operations where laser meters are impractical across open ground.

Fencing and Landscaping Contractors: Calculate linear footage for fencing bids, irrigation runs, or edging installations on residential and commercial properties without stopping to stake tape endpoints.

Municipal and DOT Field Work: Document pavement markings, signage spacing, ADA compliance distances, and right-of-way measurements with a tool that meets the pace of field inspection work.

Frequently Asked Questions

Does the SitePRO RS312 measure in feet and inches or metric?: The RS312 measures in feet and inches. The 5-digit mechanical counter displays measurements in increments up to 9,999 feet 11 inches per reset cycle, which is standard for North American construction and survey applications.
Do I need batteries to operate the RS312?: No. The RS312 uses a fully mechanical counter with no electronic components. There are no batteries to replace, no displays to fail in cold weather, and no charging required — the wheel is ready to use every time you pick it up.
Is the RS312 accurate on loose gravel or uneven ground?: Yes. The 12.5-inch diameter wide rubber tire is specifically designed to maintain consistent contact and resist sinking on loose gravel, compacted dirt, and rough concrete. Larger diameter wheels also reduce the proportional impact of small surface irregularities on cumulative measurement accuracy.
Can the handle be adjusted for different user heights?: The RS312 features a fold-flat handle designed primarily for compact storage and transport. For ergonomic field use, the handle locks in the operational position. Users requiring extended handle adjustability should consult the full SitePRO measuring wheel lineup for telescoping handle options.
