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)


Perfect replacment for th eused cargo box we picked up. With this hardware and a little cleaning it was like getting a whole new roof-top storage box. Would recommend!


Great kit. Four of the knobs were on backorder but etrailer shipped them as soon as they became available.


I have a 2003 Acura MDX and a outdated Thule carrier.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.


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. is early favorite based in past performance.


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.


Arrived exactly as described. Fits my Thule cargo box perfectly!


Replaced the attachment parts of my Thule Cascade roof box perfectly. Was happy to find it all in one kit! Not sure what the sheet of black circle stickers were for. It didn’t come with directions so I had to go by what I could see with the old parts.

The 15 Round stickers for covering mounting holes in the box, helps keep out debris.

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.


I have not mounted the box yet but this hardware looks like it will do a great job.


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!


Product was exactly what I needed for a 12 yr old Thule box. Easy buying experience and surprisingly fast delivery considering Covid, supply chain issues, etc.


They were very helpful in identifying the right package for my needs, which was to have new hardware for my old Thule Classic box that would fit the integrated rack for our Audi Q5. The package arrived yesterday and it is installed and it works perfectly. Etrailer rocks!


My girlfriend bought a used Thule on Facebook Marketplace. The sellers did not have the accessories to mount it. They told us they would find them and let us know. Weeks later, no response. We searched online for hours and found Etrailer had what we needed. They had the right accessories for what we needed and had them delivered on time, before our camping trip. Thank you for doing it right the first time and giving prompt delivery. You were a lifesaver.


Exactly what I needed for my older Thule Weekender cargo box. My old parts were rusting pretty bad and these are the exact same but newer as a replacement.


Very good product. Exactly what I needed. My old mounting hardware had rusted away and made it difficult to put the Thule Cargo Box on to the car. The Quick mount hardware was easy to install (approx 15-20 mins).


I had not used my Thule Mountaineer in over 16 years, taking a vacation where it is needed and cant find the hardware. I was not relishing having to cobble something together to be able to use the Thule. So was pleasantly surprised that etrailer carried the hardware kit and ordered immediately. It came today, complete and I'm ready to mount the Thule for vacation...thank you


We were thrilled to find replacement parts for our older Thule box. Etrailer has great customer service and wonderful reps to answer your questions. We heartily recommend doing business with these folks, great price, great product, great customer service.

One year out and all is great!

This hardware kit was perfect for our Thule Cargo Box. The kit was complete and everything has work great! etrailer has been a great resource for us!

One year later, our Thule box parts are working great! Thanks!

Fast delivery, good follow-up from the seller. No directions included in the box, but plenty of resources could be found online. Seems like a secure way to fit my old Thule cargo carrier to a new Thule rack, and it was pretty easy to put it all together.

One year later, this system works perfectly and feels very secure. Glad I found this product.

The parts fit perfectly and have extended the life of my roof carrier tremendously! And arrived quikcly!


In 2001 I bought a Thule Frontier cargo box and I have been using it ever since.
The box has given great service over hundreds of thousands of miles, but I recently bought a 2015 Chevy Equinox and needed to adapt the old box to the more modern
roof rails of my car, using my 2009 era Thule Aero Bars.
>With the help of eTrailer's great web site I was able to make sure that the product they offered would fit properly (putting an old box on a newer car is a challenge).
I ordered the parts and they arrived promptly. Everything I needed was in the kit.
The rusty bolts and deteriorated pads of the old box were easy to replace, and the whole rig is stable and will work fine for years to come.
>Thank you, eTrailer!.


Exact replacement kit for the mounting hardware of my older Thule Frontier box. The old hardware was rusted to the point it looked it would brake while driving.

Installation was about 20 minutes (including taking off the old HW). Instructions were provided at the product page, but honestly, the process was so straight forward that those were not needed.

Personally, I leave the box permanently attached to the carrier. If I had to take it off every time after use, I'd consider a newer Thule box that works with the EZMount hardware. (Mine only works with the QuickMount HW, so that wasn't an option.)


Our 15 year old Thule Cascade ski box was badly in need of some new hardware (bolts and mounting plates) as the originals had corroded severely over time. Rather than buy an entire new box, ordered a kit from etrailer. I just installed it today and could not be more satisfied! The fit was perfect and they were delivered to us as promised....I would definitely recommend etrailer to friends and family and to anyone reading this review :-)


Could not be happier with the product and service they offered.
I need this right away and the customer service people I spoke to went above and beyond to make it happen.
