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 Inch pre-wired trailer connector power supply for quick, plug-in operation. Mounted into an A-frame coupler, the jack can power 3,500 Pound of tongue weight up to 18 Inch, with another 6 Inch 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. .
