Dutton-Lainson Company - Swivel Marine Tongue Jack (6400) - Rust-Resistant Finish for Boat, Towing & Other Trailer Applications - 1000 lb Capacity, 10" Total Travel, 6" Heavy-Duty Wheel - Made in USA

Installation was quick and easily. Strong hardware. A deep socket wrench helps. The jack swivels easily and works great

This is a good, strong jack. Everything works smoothly and securely. Nice and stiff, the wheel rolls well. I wish it had a true caster instead of the wheel having the rotate the pipe, but all the ones at this price-point seem to be built this way. This is an American company that you can find and read about.

This was an exact replacement for the jack on my 2021 Yamaha 19-ft boat trailer. Works great.

This is my second Dutton-Lainson tongue jack... first one is on my 16' fishing boat trailer, been using it for 3 years with no issues. The second one I just purchased I just installed on a 10' enclosed utility trailer (Wells Cargo), so I can wheel it around in tight spaces. Installs very easily with 4 bolts and nuts. Swivels down easily, cranks up and down like it should. Great item. Only small complaint is that there's a lack of installation instructions. First time I had to go to YouTube. For my second one, I just took a photo of the jack on my boat trailer and used that as a reference for installing.

I had a Dutton Lainson tongue jack installed on my Roadrunner boat trailer when I purchased the boat. I broke the hand crank while working on the trailer. Totally my fault and not a defect with the jack. I got the manufacturers' name off the jack and order a replacement on line. It arrived on time and was almost what I had hoped for. My jack was welded on the boat frame and the jacking part was attached with a large slip ring. My plan was to detach the broken jack and installing the new jack by removing the slip ring. This new jack was attached to a bolted bracket to install onto the trailer frame. I installed the jack next to the old jack welded plate and it works perfectly.

The jack is well make and was easy to install.

But that’s expected. I can’t speak for durability, ease of rolling or lifespan. It holds the tongue of my wife’s trip-toon trailer off the ground, as expected. Isn’t bent out of whack like the old one. Cranks and turns easily. I’d buy another if needed.

Heavy duty pivoting tongue jack fits my Lund boat trailer perfectly. Easy to install and operate. The pivoting mechanism is simple and effective with some versatility in the installation so read the directions first. I mistakenly left my old one down and towed the trailer a few yards before I realized it was still down. This was a replacement and it fit perfectly. I contacted Dutton-Lainson and their help line was great about making sure I ordered the right replacement jack and got the right parts.
