If you’ve ever fought with a swing-up jack hitting a toolbox or winch post, this one’s built to solve that. The Dutton-Lainson fixed-mount jack sits tight against the trailer frame and retracts fully without needing to pivot out of the way. It works perfectly on setups with cluttered or short tongues where space is at a premium. With a retracted bracket height of 10" and extended height of 25", it moves smoothly through 15" of lift and stays clear of accessories that a swivel jack can’t get past.
Moving a trailer by hand is simpler when the wheel keeps up with you instead of fighting every turn. The 6" caster on this jack spins a full 360°, so you can push or pull your trailer into tight spots without wrestling it. It’s a handy setup for fitting into garages, storage areas, or narrow driveways where a tow vehicle can’t maneuver easily.
Saltwater and road spray are brutal on metal, which is why this jack uses Dutton-Lainson’s TUFFPLATE zinc finish. The triple-layer coating—sealed zinc, chromate, and an added barrier—stood up for nearly 500 hours in salt spray testing before showing any rust. That’s about 30% longer than standard powder coat finishes. Designed for marine use, it resists corrosion from freshwater, saltwater, and humidity, keeping the steel body looking clean and working smoothly for years.
There’s no need to pull it apart just to keep it smooth—this jack includes a built-in grease zerk to make maintenance quick. A few pumps of grease keep the sidewind gears turning easily under load. The durable steel build carries up to 1,000 lbs of static weight, and the sidewind handle gives you good leverage without mashing your knuckles on the trailer frame.
Installation is straightforward. The included mounting bracket and hardware clamp securely around trailer frames up to 3" wide x 5" tall. Once bolted up, the jack weighs only 17 lbs but adds serious convenience every time you hitch or move your trailer. It’s backed by a 3-year limited warranty for added peace of mind.

Very nice jack. Seems like it’s well made. Mounting was easy. When the package arrived the mounting hardware was missing, etrailer immediately sent replacement mounting hardware and I got it in 2 days. As usual, excellent customer service from etrailer.
I bent my boat trailer jack accidentally and needed a new one. So etrailer was there for me with this very nice Dutton-Lainson version similar to the one I had. Works great, very smooth gearing, and it looks good on my boat trailer too.
This trailer jack is just what I needed. The range is fantastic, the handle is comfortable and raising and lowering the boat trailer has never been easier
High quality and heavy duty jack. I’m hoping the quality and the grease zeros will make make this Jack last for a long time.
This jack is solid as a rock. Totally recommended. I did remove the wheel and just screwed the bolt back into the bottom of the tube for better clearance coming and going into steep driveways.
Best jack I have ever used. Holds up nicely 2nd year no rust.
Well made in the USA
Replaces the same from 09’ but a much nicer finish and zerts!
Great jack makes unhooking my 2 boats a lot easier. Jacks that come with most trailers are low bid junk.
I love this jack! I bought it for my 1984 Ski Nautique single axle trailer. Works great and looks good.
I was originally trying to find something that would bolt upto the Shelby welded bracket. I'm so glad I went with this unit instead. It's heavy duty, large wheel for easy maneuvers, greese fittings, easy up like butta! The black color is different and goes well with my red Stingray. The customer service is over the top!
This trailer jack is a huge upgrade from what my boat trailer originally came with. I love the fact that is has a caster style wheel so the boat can be easily moved around in my shop! I highly recommend it and to be honest this is all you need to spend to get a good quality jack.
Very well built jack and looks great too. Installation was a breeze. Your tracking information from the time of my order to the time it was delivered was awesome! Thank you for such great service
I just installed it and have not actually used it yet, but it looks to be extremely solid and well-made and I really appreciate the extended jacking height and the two ZR fittings to allow easy grazing.
The three year warranty, also speaks volumes about the confidence they have in this product
Glad I spent a little extra for this quality product and I think it's going to make life much much easier jacking about up and moving around
I purchased this to replace an existing jack that wasn't quite long enough. The new jack bolts on quickly, jacks up easily, and the trailer is more maneuverable with the large wheel.
Awesome product! So much better than the stock one that was there. The old jack wheel would slide and not turn on the concrete, this new one has no problem at all. Like that it's much larger and can be greased too.
This trailer jack was a near perfect duplicate of the jack I replaced. The plastic top was the only noticeable difference. I looks great! It was easy to install! I’m looking forward to keeping this one in better condition over its life. Overall, I would recommend this product as a replacement up or down grade to your existing boat trailer jack.
i purchased this as it was the same brand and size of the jack I was replacing. The original was 3 years old and no longer worked without extreme effort. The replacement was easy to install. I does have a little play in it when mounted but seems sturdy with load. It doesn't look like a better product than the original so I doubt it will last any longer. Cranking it is now functional with the new one but not as easy as I would hope for. it still takes considerable force to crank but doable where the one i took off stopped working without extreme effort. Im wishing I would have purcahsed a bigger one. maybe 2000lbs would have made a difference, not sure. I didnt see one that was bigger that looked like would mount up so I was safe and selected the same as before. Before and after pictures below. Etrailer shipping was great though. I have used Etrailer a few times and never have been disappointed in them.
Great service. Quick.
Once wheel is in the air, it spins around unless you hold it with your foot. I have not had that problem with other trailer jacks.
