The Thule SquareBar Evo is built from galvanized steel, giving it the strength to handle serious loads. With a 220-lb weight capacity, it’s ready for kayaks, canoes, or a cargo box full of camping gear. The sturdy bars don’t flex under pressure, so you can load up for long trips knowing your setup will stay solid and secure the whole way.
Each crossbar is wrapped in a polymer coating that grips your gear and guards against corrosion. That extra layer helps keep accessories from shifting during travel and protects the steel underneath from road grime and weather. It’s a small detail that keeps your rack looking good and performing well season after season.
The 47" square crossbars work with a wide range of clamp-around carriers, from kayak cradles to cargo boxes and ski racks. If you already have accessories built for square bars, they’ll mount right up without special adapters. This makes it easy to move from one adventure to the next without swapping hardware.
For added peace of mind, you can use Thule’s One-Key System locks (sold separately) to secure the rack to the vehicle. It’s a simple upgrade that helps protect your investment when you stop at the trailhead or leave it parked overnight on a trip.
This setup includes two SquareBars, four Evo Flush Rail feet, and a custom fit kit designed for flush rail installations. Everything works together as one system for a clean, reliable mount that looks like it belongs on your roof.
Ratings & Reviews
There was a delay because of pending stock, however, communication and order status transparency was excellent. And as soon as stock was received I was well informed via email and order was shipped expeditiously. Roof Rack Feet were perfect for my Volvo V60!
This is the second time I have gladly used etrailer!
Perfect fit and easy installation. Highly recommend for a lower profile rack. Also allows sunroof to vent on 2016 Lexus RX350. Haven’t driven with them on yet so I don’t know how road noise is at this time.
The packaging of the product was damaged when delivered, but eTrailer quickly replaced the two missing parts no questions asked. Great customer service and I appreciate working with the knowledgeable experts at etrailer to make sure everything I order works together.
Very sturdy. Works well. The attachment to the roof rails on my 2023 chevy suburban works well. The "C" clamp design mechanism holds it tightly and securely in place. No fear of anything coming loose and falling off like other racks I have tried to use.
The online tutorial was excellent and I was able to install the roof rack myself. The only disappointment is my board loader doesn’t work with the flush mount system.
Love Thule products!
This is the first top of the line roof rack system I have purchased. I never expected to have issues but this thing is so universal, with gaps everywhere, that I can’t get it to stop whistling. I wish I could return and get my money back. I really expected something better from such an expensive system.
The Thule SquareBar Evo Crossbars, Rapid Traverse Feet, and Fit Kit for the Roof Rack Feet were all promptly shipped and delivered within three days of the order. I had them all assembled and installed on my Ford Focus in less than an hour.
I really wish I had paid more money for more aerodynamic crossbars. These are extremely noisy and have made a noticeable difference to my gas mileage.
Thule products are not the cheapest but they are just so well engineered it brings a smile to your face every time you assemble them. I have 7 year old aero blade bars and bought these foot packs (and fit kit) for a new car. Taking off the old feet off the bars was flawless - every part, whether plastic, rubber or metal is still perfect after 7 years of use and shed storage.
Etrailer were fabulous as usual - initial phone consultation to confirm feet will fit old bars and then quick online ordering etc.
etrailer was the only place that was able to provide a solution for me! I have a 2022 GLC Benz with panoramic roof. I spent many $$ for Benz’s own cross bars. They looked great…integrated with the roof seamlessly. But I couldn’t open the panoramic roof! MAJOR FAIL!!
etrailer customized a set of Thule cross bars that not only work with my panoramic roof but are quieter and look even better than the Benz product. MAJOR AWESOME to etrailer. Now listing my Benz cross bars on Craigs.
This was the best price I found for the roof rack. My order arrived with a torn box which was UPS's fault so I was missing the end caps for the bars. When I called in a very friendly agent helped me and sent me the replacement caps free of charge and kept in contact with me until I received them. I will definitely buy from here again.
Thule makes great products
And etrailer makes it too easy to get when needed.
etrailer.com was excellent to do business with. Their website is informative, complete and easy to navigate. Phone service to help confirm availability of my product and their general knowledge of their products was impressive. Product arrived on time and in good shape. Their order tracking system is also very good. I’m very pleased with the Thule Wingbar Evo 135 racks For my BMW X5 with flush roof rails. They are super sturdy, solidly mounted and look good on the vehicle. Mine will be mainly used for surfboards and SUP’s. The assembly and installation was a breeze. The included written instructions would have been sufficient for a seamless installation but I also watched one of many YouTube videos that demonstrated very clearly every step of assembly and installation for this specific set of racks.
Love the racks!! I highly recommend etrailer.com for your roof rack needs.
I ordered the Thule WingBar Evo Crossbars - Aluminum - Silver - 50" with the Evo Flush Rail Feet for Thule Crossbars - Flush Side Rails and the Fit Kit for Thule Evo Flush Rail and Edge Flush Rail Roof Rack Feet for my 2020 Mazda CX9. I appreciated the product selector to make sure I was getting all the correct parts. I was happy with the products, but I did run into an issue where 1 of the rail feet had a defective bolt which required a replacement. I was very satisfied with etrailer's customer support, and how well they worked with me to get the part replaced quickly. I'm giving this a 4 start only because of the hassle of receiving a defective one initially
Very pleased with order. Shipped fast, not damaged, all parts accounted for. Easy install, very sturdy, and attractive design. Slight wind noise but that was expected compared to not having a roof rack.
Easy to assemble and install. Love the way etrailer packages everything you need and they all are correct for the vehicle you are mounting them on. Once installed they appear very strong. Installed on a 2023 Chevy Tahoe and did not interfere with the sunroof.
Easy to install, took less than 30 min.
Perfect fit on a Volvo V60 CC.
No issues with a "trunk" mounted bike carrier secured to the rear bar. Yakima Frontloader also fit perfectly.
I’ve had it on my 2021 Kia Telluride now for a few months and it works great. When I was mounting the forward bar, I opened the sun roof to make sure I was comfortable with the roof window and bar clearance.
Rock Solid and good looking. Expensive but worth it!
Thule Rack looks awesome on my Kia Telluride. Products took a while to get to me because they were on backorder but it's not etrailer, they were on backorder everywhere. I messed up one of the pieces of rubber while installing and etrailer sent me a new one at no charge. Definitely recommend etrailer.
Website is easy to use & is better at putting together the correct package than Thule’s site.
etrailer had all the parts in stock for my 2020 Kia Telluride.
Payment process was simple.
Received periodic updates from staffer on my order & could actually reply if needed.
Installing the roof rack went well. Estimate start to finish was about 2 hours. Found it best to really examine each diagram in Thule’s step by step instructions to get it all right on the first try.
Hardness part of the installation was getting the crossbars installed at the proper distances. A tailor’s soft measuring tape & some masking were great aids.
Thule has great quality and trailer is a great place to order from, highly recommend both!
It took me a VERY long time to figure out what I needed to mount my Hullivator on my 22 Subaru Outback Limited. I bought the wrong parts on round 1, and finally after 2 yrs of frustration, asked AI what I needed. I don't entirely trust AI, but it got me on the right track. I asked the 'chat' person on etrailer about the AI suggestion, and the gal who helped me, Autumn, said the feet part was correct, but to use these feet and the TH37CE fit kit. I ordered immediately. Today was the day. Of note, the fit kit has specific parts for the front and rear passenger and front and rear driver side. Pay attention to the photo directions. The parts are different for each side. On my Outback, they mount at 69cm apart on the Subaru rails (folded in) on the Thule Wingbar Evo 55" bars. The cladding and design of the Outback roof system leaves much to be desired, but this worked and I'm looking forward to FINALLY using my Hullivator.
