When you’re packing up for a weekend on the water or a long road trip, you want bars that can actually handle the load. The Thule SquareBar Evo is built from galvanized steel with a polymer coating that provides extra grip for your cargo and helps prevent corrosion. Each bar supports up to 220 lbs (always follow your vehicle’s own roof load rating), so you can load it up with confidence for kayaks, paddleboards, camping gear, or a cargo box full of luggage.
If you’re leaving your setup parked overnight, it’s good to know you can lock it down. The Evo Flush Rail feet accept Thule One-Key System locks?(sold separately) that deter theft of the rack itself. It’s an easy upgrade that lets you secure both the base rack and your attachments with a single key set, adding peace of mind when you’re out exploring.
Whether it’s a kayak cradle, bike rack, or cargo basket, these classic square crossbars work with accessories and carriers that clamp around the bars. There’s no need to hunt for specialized hardware—just use the mounts you already have. That straightforward compatibility makes it simple to switch between setups for every season or trip.
The polymer coating on each 47" x 1-1/4" x 7/8" bar isn’t just for looks—it provides grip for your gear while shielding the steel beneath from scratches and rust. Even after years of hauling wet boats or dusty camp gear, the bars stay reliable and ready for whatever adventure comes next.
The included Evo Flush Rail feet and custom fit kit secure neatly to flush rails on your roof. The result is a solid connection that feels factory-tight and stays put through highway miles and rough backroads alike. It’s a setup built for people who’d rather spend their time traveling than fussing with gear mounts.

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.
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 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.
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!
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.
What a great experience! I spoke or corresponded several times with representatives about technical or ordering issues, and they were uniformly very helpful and courteous. They matched a small difference in price from another vendor and were really helpful in making the decision about what to buy. The Thule items are really high quality and, in spite of instructions that would make Ikea embarrassed, weren't difficult to assemble and install. (I recommend checking for relevant videos online.) I give etrailer.com and the parts an unqualified 5-star rating. One of my best online experiences ever.
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.
I had an older version aeroblade roof rack set from Thule and looked online to check and see if there were any feet and fit kits that would use those bars (no longer in production) and fit on my 2017 Kia Niro. Found an article on etrailer that had all the info, put in the order, received it today, assembled everything in no time flat and had the roof racks, fit kit and feet installed on the top of my car within 15 minutes total. Can't ever go wrong with Thule. There's a fit for every car.
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
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.
Rock Solid and good looking. Expensive but worth it!
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.
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.
Perfect fit. Easy to install. Excellent customer service and prompt shipping. These guys are great!! THANKS JEREMY!!
