The Electric Jack with Wireless Control from Buyers Products offers you an electric-powered solution to raising, lowering, or leveling your parked RV or trailer. It has a 48 in. pre-wired trailer connector power supply for quick, plug-in operation, and also includes a wireless pendant control for user convenience and ease of use. Mounted into an A-frame coupler, the jack can power 5,500 lbs. of tongue weight up to 18 in., with another 6 in. available by releasing a manual drop leg extension. The jack features a built-in leveling gauge and an LED night light. Its oversized zinc-plated foot prevents divots. A corrosion-resistant black powder-coated finish and weather-sealed switches protect the jack from the elements. Should you need it, a manual crank can be used in place of electrical operation. 5333510: 3,500 lbs. tongue weight capacity 5335510: 5,500 lbs. tongue weight capacity. Material: Carbon Steel.
