I can't believe I found this part at your store. Thanks, Completes the project!


This was arguably the best online/mail order experience ever. I didn’t even know what replacement part I needed to make my Yakima Skybox work again, but knew and led me right to it. Never heard of a barrel nut before I needed one. I would highly recommend for all your travel equipment needs. They can handle any question you have.


Exactly what I needed.


Fit perfectly


This hard to find barrel nut was well packaged and shipped promptly. It fit the Yakima rack perfectly and now the rack is back in service. Now I am going to order a spare nut just in case. Thank you for a great transaction!


Just got the item finally. Appreciate your quick response and action. Thank you.


These are easy to lose if you loosen them too much in the box. Replacement did the trick and I ordered an extra or two.


etrailer was a pleasure to work with. At the last minute before a trip we realized that we were missing a part. We found the part on etrailer and were able to express ship in time to travel. The customer service was extraordinary. When I called to check the order, a person answered my call immediately- no endless hold time. I relayed our situation- needing either a part or a new skybox in a matter to days. She personally checked for the part, that it was in stock and out for shipment. She even followed the progress of the shipment and gave me updates. I later received a note (from a human) letting me know even more details around shipment. Without etrailer, we would have been either jamming our car with skis or running around to find a new skybox at the last minute. Thank you etrailer for your customer care and service!


Got me the correct part to repair my Yakima topper quickly and at a fair price.


Hard to find barrel nut was as described and shipped promptly. Fits Yakima rack perfectly. Great transaction. Thanks!


exactly what I needed, easy to find, quick delivery


Quinn was very professional and polite. He found the part I needed and made sure the order was processed quickly and it arrived in time for a critical family trip. Great company!


I can use my roofbox properly again!


I am grateful that etrailer had these parts available or my $200.00 cargo carrier would've been worthless. The part fit perfectly and I was back in business.
Thanks etrailer.

Ive had several products over the years and this one seems to work out the best so far. Ill be needing one for the other side of my SUV and Im leaning for the same one so far.


Fast delivery


Cam bearing plates and barrel nuts were exactly as described and service from etrailer is great. If you have a Yakima Sky Box and use it in cold weather, I would recommend getting extra bearing plates as they can crack. Also if you put the SkyBox on and off your car, some extra barrel nuts might be useful as well. That's what happened to me - putting the SkyBox up in the garage, a barrel bolt fell out and could not find it. Luckily I had a temporary nut to get me through until I got the replacements. One note, replacing the barrel nut is not as easy as you would think. It took me almost an hour to replace two barrel bolts as the design on the SkyBox is not great - you would think an industrial engineer would design the arm that grabs the cross rail so that the barrel bolt could only go in one way and that the tightening nut from inside the box could only enter into the bolt opening but no - you have to do trial and error and lots of it before the nut actually engages the bolt. It's a bit maddening. So after you get that on, do not loosen the arm too much or you will lose the bolt and you'll have a heck of a time replacing it.


Good product, I would have engineered the locking devise so it’s easier to lock down on the ski racks. Also during my first use I unscrewed the tightening screw too far an the nut fell out and was lost. I had to order a replacement. There could be some sort of device on the nut to keep it from falling out when this happens . Overall very durable product.


Shipping was prompt and item was just what I needed!


Exactly what I was looking for!



Product is still working as expected. It was difficult the locate this specific item until I was referred to etrailer. Really pleased with the ion and availability of items on etrailer. Thanks again.


Received my product in a very reasonable time via US mail.
It was a small part for my Yamaha Skybox, but important to me.
I would use etrailer again.
The part itself is a part of a poor design by Yamaha. They could have easily made the casing for the part such that the little part would not easily fall out.
Otherwise the Skybox is great.

After a year the Yamaha Skybox is as good as new. It does require another person to help me put it on my Outback, but it is light - just awkward for one.


Extremely happy with etrailer & will use and recommend them for future parts replacement.
I received better technical support from Jean at etrailer than I did at Yakima directly!
Reasonable price & quick delivery.....

Still going strong- Ill let you know after my upcoming trip to WV.


I was missing a small part of my car travel rooftop box, making the pod unusable. It's over 10 years old, has travelled across the country and back, and has been on many adventures like an old friend. Because of it's age, it's been difficult to find the part that I needed, and etrailer came through. I got the parts quickly for a reasonable price, and my pod and I are off having more adventures. Hooray for etrailer!


I was super excited to find the barrel nut for our car top box. The price was great, they shipped the product right away. Very Happy Thank you!


I have been an etrailer fan for many years, and all I can say is that after searching everywhere for this lost Yakima barrel nut, not only did these guys have it in stock, but shipped it and got me back on the road in just a couple of days!! Thanks again - etrailer. . . . and yes, it was exactly the right part.


Delivered on time, worked great for what I needed.

I needed to replace some of the barrels on my yakima sky box, this product was the best one I could find for that purpose. My sky box didn't actually need the longer barrels, but the short ones were perfect. Good price too. Would recommend if you need new barrels.
