TowPilot Trailer Tongue Weight Scale - 2200 lb Capacity, Trailer Tongue Scale for Travel Trailers, RVs & Campers, ZEROLOCK Precision Calibration System for Boat & Cargo Trailers - Silver

ZEROLOCK True-Zero Accuracy: Recalibrate the trailer tongue scale back to true zero with the integrated adjustment screw, restoring factory accuracy and preventing the drift found in other scales.
Built For Safe Towing: This 2200 lb hitch scale reads tongue weight precisely to help prevent sway. Q255 steel and a military-grade spring keep this trailer scale working in any weather, no batteries.
Camp More, Worry Less: Check tongue weight in seconds, no vehicle hookup. Set the trailer hitch tongue weight scale under the coupler and lower the jack; the top plate will not mar your coupler.
Will It Fit Your Setup?: At 20.5 in tall, your coupler must raise that high for this RV trailer tongue weight scale to fit beneath. Needs level ground. Works with any receiver or weight distribution hitch.
Never Pay for Weighing Again: Includes the TowPilot tongue weight scale for travel trailers, campers and utility rigs, a waterproof bag and a guide. Reads 300 to 2200 lb, fully assembled.
