The Vevor trailer jack is a heavy-duty swivel-mount jack designed to provide stable lifting and support for boats, RVs, horse trailers, and utility trailers. It features a 1000 lbs load capacity, a 10.2" stroke, and a 12.8" to 23" lift range for versatile trailer applications. The corrosion-resistant alloy steel construction is built for durability, while the PP caster wheel allows smooth 360-degree movement. An ergonomic handle helps make lifting and lowering easier. The swivel design folds up when not in use for added clearance and convenience.
