Product details:

Replaces your boat trailer's old swivel jack. Includes a base plate in case your old one is rusted out, but the mounting bracket is sold separately. Premium zinc finish has a 600-hour salt spray rating is ideal for trailers near saltwater. So, the more you tow around it, the more you need to protect your trailer from it. The Z-Max zinc finish on this jack offers great corrosion protection, even with occasional use around saltwater. Rust-resistant coatings are graded according to a salt spray rating. Basically, this rating shows the amount of time it takes for a material to show signs of corrosion when exposed to pure, continuous salt spray. Traditional zinc plating typically begins to deteriorate after about 100 hours. Dacromet usually lasts for around 300 to 400 hours. Fulton's Z-Max finish lasts for 600 hours in the salt spray test - 30% longer than a standard powder coat finish. The environment this test creates is much harsher than anything you'll ever experience in your journeys, but it provides a testament to how well this jack resists rust and corrosion. How to Determine the Lift Capacity You Need in a Jack A trailer jack lifts your trailer high enough at the tongue to allow you to couple it with your vehicle. Usually, your tongue weight is about 10-15% of your gross trailer weight (GTW). For example, a 10,000-lb trailer has a tongue weight of 1,000 lbs to 1,500 lbs. To raise the tongue of a trailer this size, you'd need a jack that can handle a static load of no less than 1,500 lbs. And, yes, it's okay to have a jack with a weight rating that is higher than your trailer's tongue weight. In fact, a jack with a higher capacity should operate more efficiently, allowing you to spend less time cranking and more time fishing.
