Stanley 22.2 x 15.2 x 9.3-inches Spoked Heavy-Duty Walking Measuring Wheel, Model 1-77-109 About this productThe Stanley FatMax Heavy-Duty Spoked Walking Measuring Wheel is a lightweight, commercial-grade field measurement tool engineered for high-accuracy surveying, layout zoning, and road construction. Design and Features:Lightweight Steel Spoke Configuration: Fabricated with a rigid steel spoke wheel architecture that reduces tool weight to 2.39 kg, ensuring smooth handling and effortless cleaning on mud-heavy jobsites. Weatherproof Precision Counter: Features an impact-resistant, sealed odometer housing that protects the internal gear drive from moisture, debris, and dust while tracking meters and centimeters up to 10,000 meters. Integrated Brake and Folding Handle: Equipped with a positive handle latch and mechanical braking system to halt data tracking instantly at exact endpoints, paired with a handle that folds down to 40 cm for compact storage. Product Specification:Brand: StanleyModel: 1-77-109Application: Outdoor layout surveying, landscaping, utility routing, and general construction trackingMaterial Composition: Powder-coated heavy-duty steel frame and spokes with a hard Nitrile Butadiene Rubber (NBR) tire tread.Finish: Industrial anti-corrosion, abrasion-resistant powder coatingColor: High-polished metallic silver steel spokes with a black tire and housing, accented by signature yellow branding decals.Assembled Footprint Size: 22.2 x 15.2 x 9.3 inches (56.5 x 38.5 x 23.5 cm)Folded Storage Height: 15.7 inches/40 cmWheel Circumference: 1 meter/3.28 feetMeasurement Limit: 0.00 to 9,999.99 Meters (Displays meters and centimeters)Net Tool Weight: 2.39 Kilograms (5.27 lbs)Included Components: Heavy metal fold-away kickstand, mechanical reset lever, and built-in handle brake.  Instructions for use:Unfold and Reset: Swing open the folding handle until the positive safety latch clicks securely into place, then depress the oversized manual reset lever to clear the counter to zero. Walk a Straight Path: Position the bottom center of the spoked wheel precisely at your starting line and push the tool forward at a steady walking speed, ensuring the shaft remains perpendicular to the ground to keep tracking true. Lock the Endpoint: Squeeze the hand brake integrated into the handle grip the exact moment the wheel hits your destination marker, holding the wheel fixed so the display numbers do not slip while you record the data. Precautions for use:Clean the Rubber Tread: Regularly clear out rocks or heavy caked mud that wedge into the NBR rubber tire tread, as a thick outer coating falsely enlarges the wheel's circumference and skews your distance calculation.Do Not Vehicle Tow: This hand-powered unit is strictly rated for human walking speeds; pulling it behind cars, trucks, or ATVs will instantly destroy the high-precision internal counter gears and warp the steel frame.Avoid Submersion: Never submerge the odometer hub in deep puddles or wash the unit down with high-pressure water streams; the housing is weather-resistant to light rain, but high-pressure ingress can fog the display window.
