You'll Need More than Just Zinc to Fight Rust

The simple truth is that salt can be highly corrosive to metal when exposure lasts for an extended period of time. So, the more you tow around it, the more you need to protect your trailer from it.

The TUFFPLATE finish on this jack helps to ensure that it doesn't end up looking like the one pictured above. TUFFPLATE offers 3 layers of corrosion protection. The first layer is a specially formulated zinc finish. The second layer is chromate. Finally, a sealer puts a third barrier between the jack's gleaming good looks and anything that can contribute to rust, like freshwater or even saltwater exposure.

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. Zinc plating typically begins to deteriorate after about 100 hours. Dacromet usually lasts for around 300 to 400 hours. Dutton-Lainson's TUFFPLATE finish lasted nearly 500 hours in the salt spray test before the first appearance of rust (about 30% longer than a traditional powder coat finish). As for the first appearance of white corrosion, it performed about as well as typical zinc finishes.

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.
