Features to know about
Smooth Lifting and Easy Maneuvering: 15" Lift with 6" Caster Wheel
Hookups, parking, and shifting your trailer by hand get a lot simpler with the smooth-cranking sidewind handle and 15" of lift. The built-in 6" caster wheel rolls easily for small moves or alignment, and it can be swapped out for a foot plate (sold separately) when you want more stability on soft ground. The cushioned grip makes cranking comfortable, and the handle clears tool boxes and winch posts without getting in the way.
Built to Resist Salt and Spray: TUFFPLATE Zinc Finish with 500-Hour Rating
Saltwater and road grime won’t eat through this jack. The premium TUFFPLATE zinc finish uses three layers—a zinc base, chromate layer, and sealed top coat—to block corrosion. It held up for nearly 500 hours in salt-spray testing, which is about five times stronger than standard zinc and outlasts typical powder coat. That means less worry about rusting hardware or frozen parts, even after repeated dunking or coastal use.
Reliable Support for Light and Mid-Size Trailers: 1,000-lb Lift Capacity
With a 1,000-lb capacity, this A-frame jack easily handles typical tongue weights for small campers, boats, or utility trailers. The bracket height ranges from 8-1/2" retracted to 23-1/2" extended, so it gives you plenty of lift to level or hitch up. Both the inner and outer tubes—1-3/4" and 2" in diameter—are made from durable steel for steady support without flexing under load.
Quick Retrofit and Solid Fit: 2" Outer Tube with Bolt-On Hardware
Replacing a worn-out or hard-to-find factory jack is straightforward thanks to the 2" outer diameter and included bolt-on hardware. It drops into the existing hole on most standard A-frame couplers without drilling new holes. Installation takes just a few minutes, and once bolted up, the jack sits tight and turns smoothly.
Ready for Years of Use: Durable Steel Construction and Simple Design
This jack’s all-steel build and sealed finish mean it’s made to last. There’s no complicated mechanism to maintain, just a dependable sidewind that works every time you need to lift, lower, or move your trailer. Whether it’s seeing weekly boat launches or sitting out the winter, it stays solid and easy to operate season after season.

It was nearly the perfect size for my 1970's trailer. I had to do a little grinding and filing to make the lower hole on the tongue the correct diameter and then jiggle it a bit to line up all the bolt holes. Thein this 62 yr old grammy fastened it down. Thanks tothe lock washers!

It was a perfect fit on a 20 year old trailer. The one it replaced was a disaster, and now I don't have to fight it any more. Solid replacement. Would recommend.

This jack is the perfect fit for our trailer with a 2" hole. etrailer.com had all the details listed (not like other sites) so that I could purchase with confidence. Strong jack with lock on (pin) wheel. etrailer.com is my new go to site for trailer needs.

The trailer jack for Our old (1996) tent trailer was received in a timely manner in good condition. It was easy to install and appears to work well. Very easy to operate and good instructions were included.

The jack is great. It was hard to find because it is for an older model pop up camper but Kurt was super helpful and helped me find the right one. This company offers exceptional customer sevice. Incredible attitudes all around. It’s like Disney world but for trailers. Never seen anything like it. I won’t go anywhere else for trailer needs.

I would only say that the retracted "up" position of the jack does NOT have enough ground clearance , absent the wheel, to guarantee there is NO contact with concrete when entering/exiting a sloped concrete driveway.

See what our Experts say about this Dutton-Lainson Trailer Jack
- 2 inch Outer Diameter A-Frame Trailer Jack RecommendationI have good news, our trailer jack that has a 2 inch outer diameter part # DL74MR would fit and work well. While it has a 1,000 lb weight capacity that does not mean 1,000 lb total trailer weight capacity. That capacity is the tongue weight capacity which is normally 10-15 percent of the total trailer weight. So your trailer would be looking at around 150 lbs of tongue weight which would be no problem for this at all.
view full answer... - Looking for A-Frame Trailer Jack with Wheel CasterHey Lloyd, there isn't a wheel option made for the etrailer Sidewind Trailer Jack w/ Drill Adapter # e88GV but we do have an a-frame jack that does have a wheel caster like you are looking for with the Dutton Lainson part # DL74MR. This will work great as a new jack that will allow you to move the trailer around as needed. What kind of trailer do you have?
view full answer... - Measurement From The Bottom Of The Wheel To The Bottom Of The Bracket On The DL74MR JackHi Robert! The Dutton-Lainson A-Frame Boat Trailer Jack w/ Wheel - Sidewind - 15" Lift - 1,000 lbs # DL74MR will measure 16-13/16" (roughly) from the bottom of the wheel to the bottom of the mounting bracket when fully collapsed. When fully extended, it will measure 31-13/16" (roughly). I say roughly for both of those as there may be a little bit of wiggle room in those measurements as I had to do the measurements for the wheel separately. We don't have the jack on hand at the moment,...
view full answer... - A-Frame Jack with Wheel Caster Recommendation for Shasta AirflyteHey Diana, there isn't a confirmed caster wheel available for the # e38AV but I do have a similar solution that will work. The etrailer jack is designed to use its included foot/SnapPad. If you need a jack that allows the trailer to be rolled around, I'd recommend switching to a jack specifically designed with a caster wheel like the Dutton Lainson part # DL74MR which will work great for you. What does your Shasta weigh? It looks pretty awesome!
view full answer... - Availability Of A-Frame Trailer jack With 1.5" Outside Diameter TubeHello J, thanks for reaching out. I went thru all of the A-frame jacks we carry and I am sorry to say we do not offer one with a 1.5" outer diameter tube. They are virtually all 2-1/4" OD tubes. The only exception is the Dutton-Lainson A-Frame Boat Trailer Jack w/ Wheel # DL74MR which has a 2" OD tube. Honestly, you might have a really hard time finding a jack with a 1.5" tube. It just isn't common anymore. If you are needing a new jack, I recommend having a new support plate welded on...
view full answer... - Is There an A-Frame Jack Wheel Designed for a 1.5 inch Diameter Jack LegHey Craig, yeah a 1.5 inch jack leg is going to be pretty small and hard to find anything that fits as most everything now is 2-1/4 inch. Do you see a brand on the jack by chance? That might be best place to start checking. For an a-frame jack with a wheel that you could use to replace what you have the Dutton Lainson part # DL74MR would be a really great option.
view full answer... - What is the Mounting Hole Spacing of the Dutton-Lainson A-Frame Boat Trailer Jack w/ Wheel DL74MR?Hey Randall. The Dutton-Lainson A-Frame Boat Trailer Jack w/ Wheel item # DL74MR has a 3" on center bolt pattern, which is standard for an A-Frame jack. The outer tube diameter is 2". It has 15" of travel, a 1,000 lbs weight capacity, and a 6" caster wheel. What kind of trailer do you have? You can add this information, along with any other questions you have, where it says Add Comment.
view full answer... - Solution for Needing Trailer Jack with Outer Tube Diameter of 1-7/8 inchI have a solution for you, however we do not have a trailer jack available that features an outer tube diameter of 1-7/8 inches. They just aren't around anymore. The best recommendation I have is to simply install a new bottom support plate like the Bulldog Jack Support Plate # BD003135. The new plate can be either welded or bolted onto the trailer and features a 2-1/3 inch diameter hole for jack tubes, making it much more universal in terms of finding a compatible trailer jack. Then...
view full answer... - Weight Distribution for Trailer With Side Mounted Trailer JackIt may be possible to use a WDH like the Equal-i-zer Weight Distribution System # EQ37100ET with your trailer, but it will depend on the location of that jockey wheel. The brackets for this system mount 27-32" back from the center of the coupler with the overall length of the spring bars being 36". If your jack is clear or can be moved so it is out of the way then you could use this system or others like it. The other possibility is to mount that jack on the inside of the frame if it...
view full answer... - Dutton-Lainson Trailer Jacks That Are Made In The USAWe carry the Dutton-Lainson line of jacks that are made in the USA. Here are a few of the different jacks that we carry from them. A-Frame Jacks 1,000LB A-Frame Trailer Jack with Caster Wheel # DL74MR 5,000LB A-Frame Trailer Jack # DL22772 Side Mount Jacks 1,500LB Pull Pin, Easy Swivel Trailer Jack with 6" Dual Wheels # DL22580 2,000LB Drop Leg Trailer Jack with Footplate # DL97MR 2,000LB Pipe Mount Swivel Style Trailer Jack with Foot # DL22682
view full answer... - Solution for Adding Wheel to Jack on 2002 Rockwood Freedom 1980 I do have a solution, but all of our wheels fit a 2" diameter tube. With a 1.7" measurement you won't find anything that fits your current jack. The only way to add a wheel will be to get a new jack like the A-Frame Trailer Jack with Caster Wheel # DL74MR. As far as I can tell, you have an A-frame jack right now so this will work as a replacement. It has 15" of travel and a 1,000 lb weight capacity which should be plenty for your camper.
view full answer... - Replacement Option For Pop-Up CamperThere isn't a replacement wheel we can offer for an AL-KO jack; the best we can do is a new jack, and I assume that is an A-frame jack. For one with a wheel use A-Frame Trailer Jack with Caster Wheel # DL74MR, which is a 1,000 lb capacity jack. If that's not right I have added a link to our entire selection of jacks for you.
view full answer... - Looking for Replacement Jack Foot Plate for Dutton Lainson Jack DL74MRHey Jessica, yes the replacement steel foot part # DL22541 that you referenced is correct foot plate replacement for the Dutton Lainson jack part # DL74MR that you referenced. Do you have the jack already?
