The standard remote control allows users to change units, clear measurements, zero and tare out weight and capture peak weight at a distance of up to 100ft. The aluminum die-cast chrome-plated steel hook includes a safety latch to make load connection easy and secure. The large upper shackle accommodates thick hooks. The reliable load cell features nickel-plated corrosion-resistant alloy steel for years of reliable service.
