This Bastion Distribution trailer jack is built to handle serious weight with ease! With a 1000-pound capacity, it can support most boat trailers and utility trailers without breaking a sweat. The adjustable height from 10.5 to 20.5 inches means it works with various trailer setups, and it fits tongues from 3 to 5 inches wide. The 6-inch swivel wheel makes positioning your trailer incredibly easy - no more struggling to line up your hitch. The side-winding crank handle provides good leverage for smooth lifting and lowering. The 1:1 gear ratio means what you put in is what you get out - no complicated gearing to worry about. The corrosion-resistant coating is important for boat trailers that see water exposure regularly. Installation is straightforward with the bolt-on design - just secure it to your trailer tongue and you're ready to go. The low friction mobility lets you move your trailer around by hand when needed. This isn't some flimsy jack that will bend or fail under load - the construction feels solid and reliable. It comes with a 6-month warranty for peace of mind. Whether you're launching your boat, storing your trailer, or just need to unhitch for maintenance, this jack makes the process so much easier and safer. It's one of those trailer accessories that you don't realize you need until you have one, then wonder how you managed without it. The quality is evident in every detail, from the smooth operation to the durable materials used throughout.
