The Buyers Products Drill-Powered Swing-Away Trailer Jack combines strength, convenience, and durability for easy trailer handling. Its 6 in. wheel rolls smoothly for simple maneuvering, while the swing-away design lets the jack fold up and out of the way when not in use. Both models (5331500 and 5331505) feature both a manual side-wind crank and a ¾ in. hex head for drill power, allowing you to use a portable electric drill for faster, low-effort operation. With a 1,500 lb. tongue capacity and a versatile bolt-on mounting bracket that fits trailer frames up to 3 in. x 5 in., this jack is built for dependable performance. Mounting hardware is included. 5331500: Zinc-plated steel construction for weather and water resistance 5331505: White powder-coated aluminum construction for superior corrosion resistance
