Replaced the froze up handle on my cargopro atv trailer,works great.
I just had to use a different lock nut for proper thread engagement for my application.


I looked everywhere and finally found the exact model of handle I needed and this one is actually much better quality than the original.


This handle replacement is not easy to find. I ordered it thinking it will be a direct replacement for my jack but im 95% sure this is designed for a larger hole than the bolt itself. It has two nibs that look like they are supposed to bind when tightening the nut which didn't work on mine so i ended up using an impact to snug it up. I also had to add two large washers as spacers because the plastic had way too much play side to side. Overall it is working just fine.


This particular handle was exactly what I was looking for, and I had unsuccessfully checked many other places for them. This style of bolt-on handle is evidently not used much anymore, so I was very happy to find it here. It is of very good quality and comes with the handle, bolt, locking nut, and flat washer. I am using it on a boat trailer jack. I thought the price was excellent.

Let me add that I was very impressed with the communications I received from Erika W. at etrailer. She emailed me right away with the apology that the handle was on backorder, and kept me up to date along the way. These communications were not the result of my inquiring about the handle - they were proactive updates from her about the delay and the progress they were making.

I have purchased from etrailer before and I certainly will again!

After a year the handle is still working great!

by: has never let me down. Website is smooth and seamless, and I don’t know how it could be any better a perfect experience every time.


Fit fine and should stay put with the locking nut. Seems to be a quality handle.


This handle was just what I needed to replace the rubber-grip rotating handle that went missing off the SeaSense jack on my boat trailer. It has a lock nut so maybe it won't fall off on the highway like the last one did! These don't seem easy to find, maybe it's an old style of jack, so I was grateful eTrailer had one to sell. I down-rated one star only because it seemed overpriced, but because I couldn't find it anywhere else, that's ok too.


I needed a new handle for my tongue jack. the jack was under warranty, but when I called for a replacement they said it was backordered until the end of october, and I should call back then just to see if is available yet. what kind of customer service is that?? I'm glad e-trailer had this handle available. It was worth the few dollars I paid for it to not have to deal with the poor service from the manufacturer!! fast shipping, and good quality part!!


Simple to install and very good quality. Replaced both the winch and jack handles. Very happy with the purchased.


Been looking everywhere for this type of jack handle. This is exactly what I needed and works great!


I have purchased multiple products from this company and I found them to over communicate which I like and also ship everything in a prompt manner very good company to do business with in my opinion


Great quality. My trailer crank needed minor modification for this handle kit to fit BUT this replacement handle is far superior in quality than the handle it is replacing. Shipping fast and intact. will be my "go to" for trailer repair in the future.

Grrrreat! Very stalwart part and has been worked hard and put away wet a lot lately. No signs of wear. I am very pleased with this part. Thanks for checking with me.

Works as advertised. Good quality


Fits perfect


I had broken off the handle on my boat trailer jack and this replacement worked great. The bolt was a little big for the crank and I had to drill the hole out a bit but it tightened down firmly and works great!

Still working wonderfully!

This was a perfect handle replacement for my Fullton sidewind trailer tongue jack. I went online to find a Fullton brand replacement handle but was unable to find one. Nice chunky ribbed black handle with a 3/8" dia thread and nylock nut. Shipping was fast.
Very happy!

Not the item I ordered. The price was high enough already. Now I have to buy more parts to make it work.

Customer Service will reach out to you.

Your service was very good ... easy to order and the product arrived on time.

The handle ended up not quite fitting my trailer (which is "not" one of the ones it is made for) ... but, I was able to "make it work" for the most part.



This is a good part and I would buy it again if I needed a trailer jack handle. The plastic is a little short for the axle bolt, but good enough to do it's job well.


I appreciate receiving the item as described and promptly shipped. The replacement jack handle was very affordable and helped me provide a repair to animal trailer in need. Installation was quick and I thank you again for exceeding our expectations!


My utility trailer jack handle was missing and this product was a perfect replacement and a perfect fit. Very well made and no complaints here. Thank you ETrailer.


I had to drill the hole out on my trailer just a little bit, but the handle works great and is exactly what I was looking for.


Excellent product. Fast shipping. I actually used the handle to repair a metal hose reel that had a broken handle. Fits perfectly and looks much more durable than the original.

Thank you!!


My handle broke on my SnowDogg Plow jack, no replacement was available. This worked better than I expected, with a slight modification near the threads it fit perfectly.
