When you’re loading up kayaks, canoes, or camping gear, you want a rack that feels solid. These Thule SquareBar Evo crossbars are made of galvanized steel, giving them the strength to handle up to 220 lbs of cargo. The steel build resists flexing and keeps your load stable on rough roads or long drives. It’s a setup built to handle real weight without wobble or sag.
Nothing’s worse than gear shifting around while you drive. The SquareBar Evo’s polymer coating adds traction so your cargo stays put. That same coating also helps prevent corrosion, keeping the bars looking clean and performing smoothly season after season. Whether it’s wet paddling gear or camping boxes, the surface helps everything stay secure.
The included Evo Flush Rail feet and custom fit kit make installation straightforward while keeping the rack tight to the roofline. The setup attaches cleanly to flush rails, giving a solid connection point that feels factory-fitted rather than add-on. Once tightened down, you get a stable base that’s ready for whatever attachments you need next.
When you park with a full load of gear on top, it’s good peace of mind to know your rack can lock up. The Thule One-Key System locks (sold separately) integrate right into the feet to help deter theft of the rack itself. It’s an easy upgrade that adds security when you leave your vehicle overnight or stop along the way on a trip.
These square crossbars are ready for almost anything that clamps around them—kayak holders, cargo boxes, ski racks, or bike carriers. You can reuse your existing clamp-on gear without needing adapters or new mounts. With 53" bars and a steel build rated for 220 lbs, it’s a reliable foundation for hauling all kinds of outdoor equipment wherever you’re headed next.

This review is about the cross bars, the towers, clamps and pads made by Thule from the etrailer site. The instructions were straightforward, and the parts were clearly identified and labelled. Installation was easy, primarily because of the availability of instructional videos etrailer provided on line. Seeing it done from start to finish made the installation quite easy and straightforward. Looking forward to using my new roof system to transport our kayak this summer! Am very satisfied.
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
I think this a great roof rack it held a Thule box on a 2019 accord to florida but one thing I think that sucks is how much it whistles when driving besides that its great!!
Rock Solid and good looking. Expensive but worth it!
The crossbars were delivered but one end of the box was ripped open during transit.The end caps on the crossbars were missing. I called customer service and the are sending me new end caps free of charge. Good cUstomer service.
The bars are nice but Thule pointedly does not include under bar cover strips with this style of bars. They include these strips with the other three styles of bars they sell. Including these strips would cut the wind noise these bars produce substantially. I overcame this omission by re-using an old 5/8 inch ID (7/8 inch OD) garden hose that I cut up and slid inside the bars from the ends.
So far so good! The ease of installation was incredible. Pop the fit kit together, put it on the bar and install. Everything is straight forward with the directions. Its even easier if you find a video of the installation. The rack definitely has a little bit of a whistle to it but its kinda expected when you disrupt the airflow. I'm going to pick up my new kayak tomorrow and couldn't be happier! Not the best photo but its all i got at the moment lol.
Classic square bar, but modern integration with the podium feet. Exactly what I was looking for.
Easy set up, great roof rack. One small problem with installing the rubber strips, piece would not lay flush..
Thule makes great products
And etrailer makes it too easy to get when needed.
Thule has great quality and trailer is a great place to order from, highly recommend both!
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.
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.
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.
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.
About a year ago we purchased two Thule Hullavator Pro kayak racks along with a Thule SquareBar Roof Rack for mounting. The combination worked out very well and we headed from Colorado Springs to Duvall Washington outside of Seattle with three stops along the way to kayak. The trip went smoothly and we appreciated the Hullavator ease lifting the boats. We have two more trips planned in the near future. We did mount the boats with cockpits down to avoid filling with water when traveling without a problem.
Etrailer is the best! Great products and service!! Highly recommended.
I have a Corolla sedan SE 2024 and putting the proper tongue into the proper feet for that particular car and then adding the bar and placing it on the car a specific amount of the distance between etcetera warrants a small, very short video for that specific car--for every specific car, otherwise you wind up taking 2 hours to do a very simple job. Also one of the bars had a slight bow in. It was not exactly straight, which made the placement even more difficult.So all in all it was only average.
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.
Perfect fit. Easy to install. Excellent customer service and prompt shipping. These guys are great!! THANKS JEREMY!!

Glad we could help, Jake! Looks good on there as well! ^___^ What kind of kayaks are you going to be carrying?
