The Vevor trailer jack is a heavy-duty bolt-on tongue jack designed to provide stable lifting for boat, RV, horse, utility, and yacht trailers. It features a 1,000 lb load capacity, a 10" stroke, and a lifting range of 12.75" to 22.75" for versatile trailer support. Built from heavy-duty carbon steel with galvanized inner and outer tubes, it is designed for strength and corrosion resistance. A PP wheel and ergonomic handle help deliver smooth movement and easy manual operation. The jack can be bolted or welded onto the trailer tongue and swings up parallel to the tongue for maneuverability.
