The 12 Volt Electric Jack from Buyers Products is a convenient electric way to raise, lower, and level your parked RV or trailer. It has a 48 in. pre-wired trailer connector power supply for quick, plug-in operation. Mounted into an A-frame coupler, the jack can power 3,500 lb 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.
