The extra-wide caster wheel offers great surface contact when rolling ofer gravel or soft ground, and turns 360 degrees for easy maneuverability. Black powder coat and zinc provide rust protection, which is great for boat trailers. Made in the USA.

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.
This Dutton-Lainson jack offers 2 layers of corrosion protection. The first layer is Dutton-Lainson's specially formulated TUFFPLATE, which is comprised of a clear zinc finish, chromate, and a sealant. The second layer is a matte black powder coat finish that puts another barrier between the jack's 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 standard 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.
The wheel on this jack has form and function. Most swivel jacks that have wheels are 2" wide. On this one, it's 3". That provides extra surface area, which translates to great stability on pavement and small gravel, and it helps to alleviate sinking in soft ground. Whether you take your trailer off-road, or it never leaves the pavement, this wide wheel has all your bases covered.
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.
