In our goal of being your excellent source for all things towing, the Curt line of trailer jacks is designed with care and manufactured with pride. Curt jacks are made with quality to promote the life and function of your trailer and they come in several different styles to accommodate your needs, whether you are a frequenter of the boat landing, the campground, the racetrack or the field. Designed to withstand the wear and tear of frequent water exposure, Curt marine jacks are the jack of choice for the avid fisherman or boating enthusiast. Our marine jacks have a few features that make them a special addition to our trailer jack line. Unlike any of our other jacks, Curt marine trailer jacks are equipped with wheels, allowing for greater mobility and easier coupling of your trailer. Choose from models with one or two wheels. Marine jacks also have a heavy-duty pull-pin that allows them to pivot on their mounting bracket to be out of the way for travel. To protect them from corrosion and the damage of moisture, these jacks come with a zinc finish.Rated for 1000 lb support capacity and 1000 lb lift capacitySide-wind handle easily raises or lowers trailer coupler6 in wheel for convenient trailer mobility and couplingSwivel bracket allows jack to fully swing up and out of the way for travelHeavy-duty pull-pin keeps jack securely locked in place10 in of vertical travel accommodate multiple ball heightsBolt-on hardware included for secure mountingProtected by a durable zinc plated finishLimited lifetime warranty (one-year finish, one-year parts)
