I haven’t installed the parts yet but they match exactly The parts from my original rooftop carrier. Everything looks great can’t wait to try it out this spring
Replacement part better than original - matched exactly. Outstanding customer service. Delivered on-time. Great experience. Highly recommend.
quick shipping and everything worked as required
Worked great! Super solid attachment to my Sienna.
The parts were perfect for my older Summit Thule car too carrier.

Fantastic….so glad there were replacements.
I updated all the quick-mount hardware on my 20+year old Thule cargo box with these replacements from etrailer. Everything was as good or better than the rusted and worn original parts, so now I’m good for another couple of decades.
The hardware was perfect, and it allowed us to resurrect a decades old to lit box for the roof!
Looks like they made improvements over the original parts
Thank you
I bought a used Thule Adventurer that needed the hardware for installation on my square Thule bars.
This is the set you need and it was easy to install. What made it easy was the video that they provide in ‘Product Details’ on their site.
I installed this in less than an hour thanks to the video!
This mountingadapter was really made for the Thule 'Adventurer' cargo box. However, with a quick adjustment (drilled 8 new holes) it also worked great on my older Thule 'Weekender' cargo box.
The quick release design works great and I would recommend it for anyone that needs to attach any box to their cargo rack.
All good, this set fits exactly on my Thulé box. Thanks a lot.
Very happy
etrailer is the best. The drawing on your site really helped (attached). I can now use my 25 yr old Thule Adventurer box on my 2019 Subaru Outback. This is the 2nd etrailer product I’ve purchased and installed, the other being a hitch for my 2012 Honda Fit. The video also was key to a successful install. Keep up the great work :0)
etrailer had an item that's getting harder to find in stock. Shipping was free and on time. Excellent service, very happy with the purchase!
I'm pleased with this purchase, the replacement brackets work as intended. Allowing me to mount my Thule Adventurer 650 Cargo Box to the stock roof rack on my 2000 Forester. With that said its worth mentioning that I did have to drill new holes in my cargo box. This was due to the internal parts of the mounts hardware (plastic brackets shown) being physically wider then the old metal plates. Not a major issue assuming you have a drill handy... If you don't, keep in mind you may need one.
I have a 2003 Acura MDX and a outdated Thule carrier. I found e-trailer on line looking for a solution. My cross bars aren't adjustable or removable. The problem was that my cross bars are too wide to accommodate my Thule Revolution's hardware. I reached out to etrailer and they had the solution. So I was informed the by buying this new hardware from another model of the Thule collection with a 3 1/2 inch with would do the trick. I wa also told that I would have to drill 4 new holes. Just like that and 4 little holes later. I'm ready to clean the clutter and go to the beach with the use of all my seats. Thanks etrailer. I already mad another purchase which I'll be leaving a review.
For future potential customers. Customer service was great with fast delivery and nicely priced items.
Was exactly what I expected and delivered on time. Was kept informed throughout the whole process. Well done.
After a year, I can recall the great price, rapid/accurate technical advice and speedy delivery. The adapter kit installed easily. The mounts have been in constant use with my Thule Adventurer Roof Top Cargo Box.
I’m researching a trailer hitch currently for a summer road trip. etrailer.com is early favorite based in past performance.
This fit our 2002 Thule Frontier 668 perfectly. We had to modify the Thule holes a little to fit a 2024 Subaru Outback but did a test drive and works great. This Thule did a lot of traveling through our kids sports years. It's been in storage since they left home. Glad we kept it because it will be heading back to California to use for adventures. The hardware had seen better times so we needed new. This package did what it was supposed to do.

The Thule made it to California without incident and has been on numerous camping trips since. The hardware works well.

Exactly what I needed. A hard to find item in stock with quick free shipping. Got me up and running for a 20 year old Thule cargo box that was hard to attach to non standard size crossbars. Thanks
Perfect replacement parts
Worked great to replace the old hardware on my Thule!
It fits on our 2001 Mercedes wagon and the old Thule box!
This was the perfect replacement parts for an older model Thule cargo box. It worked perfectly and saved us a ton of money.
Once it’s all set up it does a great job fitting my older Thule box to my Honda Pilot.
I have a 26 year old Thule cargo box that I wanted to move to my new car and new rack. This mounting kit fit my needs perfectly. My old mounting hardware was rusty so it is nice to have new hardware. Ordering, communication with and delivery was easy and I would recommend etrailer.

I now have the cargo box installed on my toy hauler trailer. I had to manipulate the existing roof rack, but the replacement parts were an exact fit from the original very smooth. Everything is in place and working great fantastic replacement kit. The old parts were definitely unusable. I would highly recommend this replacement kit.
