It is a great kayak rack for our car. It easily hold both kayaks and it is easy to load and tie down the kayaks. I am very pleased with the product!



by:

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.



by:

They work as advertised. No problems. I am giving a so-so rating because Thule should have included locking cores with their plenty expensive products.



by:

Great for locking our car roof rack. Never had a problem.



by:

Thule gear. Aero crossbars and bike rack. Built well and dependable operation. The lock cores and keys are a must. Nothing but quality items and service from etrailer.com.



by:

I ordered the one key lock system to secure my crossbars to my vehicle.they installed real easy.



by:

This is my first Thule product but not my last. etrailer was great to deal with the videos on how to install the product were so helpful. Between etrailer's help and all the reviews that other people had purchased and posted made this a very pleasant purchase and install. I highly recommend etrailer and the complete Thule WingBar system including the keylocks that worked perfectly.



by:

Great for added security, easy to use.



by:

The service I received from "etrailer" is what I expect from any quality retailer. Abigail helped me order the correct items I needed to.


The service Abigail provided was excellent! I wish more retailers would take the time to educate their employees.

The Thule One Lock System works perfectly!

The locks work well.

Very nice same key locks... I have used Yakima for years but went to Thule on my Jeep and am very pleased with the quality of Thule...

Easy to swap out old cylinders to make all locks have the same key.

Great quality and still working well after a year of use.

Ordering
process was easy as I was able to search for the set that matched with my vehicle. I originally had ordered locks along with my set, but they were out of stock. But they were very flexible in allowing me to cancel that item and have my rack set processed and shipped right away. Fairly fast delivery, I believe it took about a week or so.

Assembling it was very simple with the instruction manual if you read it carefully, there is also a helpful video if you need it. Had a little bit of a struggle with spacing out the cross bars in order for it to fit my ski carriers that I already had (but I did expect this).

The final product is actually fantastic. Immediately slapped my snowboard into it and ran it out for a drive. Peaked at 70 MPH with no issues of it falling off or wind whistling.

Definitely worth it to spend the extra money to buy quality like this. Even better when the folks selling it do a great job handling your order and shipping!

Review of Entire set: After a year of using this, it still works very well. Easy to take on and off your car and make slight adjustments if needed. Only maintaining is really just cleaning it which is simple enough. No issues with lockingunlocking with the keys. It has definitely helped saved space for my tiny Honda Civic.



by:

Great products, which is what I expected. A part was missing from the original order, however due to great service from etrailer that issue was quickly resolved. Thanks again for excellent customer service.



by:

Spend the extra money on a product that will really secure your kayak so you don't have worry while driving down the road. I ditched a cheaper no name brand in favor of these and couldn't be happier.

Locks still work fine



by:

These locks fit beautifully. I'm glad that I am able to lock my roof rack. I was afraid I wouldn't be able to find the locks but etrailer was able to save the day! Thanks



by:

I originally bought the Thule T2 classic bike rack. First of all if you don’t have a platform rack you need to get one. So much easier to use. Your bikes will not get dinged up. I then bought the 2 bike add on for my rack. Because I don’t always need a rack for more than 2 it was nice that I can easily add 2 if needed. Easy to install and remove the add on. Plus you can never go wrong with Thule and e trailer.com!

Still love the rack. It’s the best money I’ve ever spent for a rack. I’m always telling friends how great the rack is and the buying experience through e trailer!



by:

My order was processed very quickly and shipped in a timely manner. Everything arrived in great shape. I am pairing my Thule crossbar kit with a Thule Force XT cargo box to increase my capacity for hauling camping gear for a family of 4 in a 2019 Subaru Forester. The installation and product review videos on your website are very helpful.

We are still using the crossbars and locking kit and they seem to be holding up just fine.



by:

Very nice and easy to install



by:

I am very happy with the Tulle carrier. However, I was missing one part that I had to call and have shipped to our destination. I spent several hours making a substitute part so that I could use the carrier to take to Florida. Everything is working now and I am waiting for the part.



by:

the Thule Car Carrier is my first purchase best decision i made to support our travel needs. we enjoy road trips and loaded the carrier with 4 suitcases and 2 large soft bags on our trip to Orlando. Easy to install and take down. did not feel the carrier on the vehicle, well balances.

Awesome, investment is paying off. Be careful with the parking garage



by:

I've been using the Thule lock system for one year now and am totally satisfied. Locks performing just like the day of installation. Good product - they keep my Thule Hullavator system secure.



by:

Once again etrailer had exactly what I needed. Even though the item was out of stock when I ordered it, I got regular updates about when it would be available. The item was restocked quickly and I received the Thule locks well before I really expected them. Great videos provided to show me how to install the locks. Great customer service as usual!

This system will give you 53" of useable crossbar space to support your roof top tent and a 165lb weight capacity. The roof top tents we offer like the Yakima Skyrise # Y07437 require a minimum...

    I do have a Thule roof bike rack to fit your 2022 Subaru Crosstrek.

You can tell if you have newer Thule square crossbars if there is a channel on the underside of the crossbars. If there is not a channel present, your roof rack will consist of the following items.

  • Is Thule Canyon XT Roof Cargo Basket a Quieter Option For Roof Basket
    While there is always going to be some noise with a rooftop basket as you know, a quieter option is indeed the Thule Canyon XT Roof Cargo Basket - Steel - 69" x 40" x 6" # TH859XT-8591XT. The reason for that is its more aerodynamic front than other baskets. Most - including your 14'er - have a more vertical front end, so even with a wind fairing attached, there is going to be more noise. The Canyon XT # TH859XT-8591XT has a more sloped, aero-shaped front end than other baskets, so even...

    I do have an option for you but I don't think you will be able to find a cargo box for a crossbar spread this large, we do not offer any unfortunately. That said, we do have cargo basket options like the Thule Canyon XT Roof Cargo Basket part # TH859XT-8591XT which is what I recommend and really your only option. You can lock the basket to the rack using the Thule One-Key System Lock Cylinders part # TH450400 but we don't really have any options to secure the contents inside the basket. If...

You can add the 20 inch extension, in part # TH8591XT and keep the same range of crossbar spreads. This roof basket offers an optional lock to secure the basket to the crossbars in part # TH450400.

  • Replacement Key for 2872 Lock Core on Sears 20SV Cargo Carrier
    I believe you are looking for the replacement key for the 2872 lock core on your Sears 20SV roof top cargo basket. For that you need the part # THKEYN2872 and you're good to go! Thule helped design the Sears boxes which is why their keys are compatible. If you need to replace the lock core then you'll need to replace your lock cores as Thule doesn't have any replacement 2872 lock cores. For the kit you'll need the part # TH450200 which comes with 2 cores or part # TH450400 which comes...

  • Thule AeroBlade Edge Roof Rack Fit for a 2011 Jetta SportWagen
    The Thule AeroBlade Edge Roof Rack, # TH7501B-TH7502B, will fit your 2011 Jetta SportWagen. The ends of the crossbars have rubber-coated steel straps that wrap around the factory side rails on your roof. This roof rack fits a wide variety of other vehicles. Since it mounts to raised roof side rails, it does not need a vehicle specific fit kit. The main factor that determines a fit is the width of the roof. If you have another vehicle that you will want to use this roof rack on, feel free...

    For your 2018 Subaru Crosstrek Thule recommends the 50 inch Wingbar Evo roof rack part # TH711300 and # TH710401. Then for a lock core kit with 4 cores you'd want the part # TH450400 and you'd be set. I attached an install video link on this page for this rack on a similar 2018 Crosstrek as well.

  • Availability of Replacement Lock Plugs for Thule Traverse Foot Pack
    I spoke with my contact at Thule and she informed me that the lock plugs for the Thule Traverse Roof-Rack Foot Pack are not available as a replacement part. The Replacement Lock Plug # 853-3160 that you referenced are designed for certain model bike and cargo carriers, so they will not fit these feet. Your best option for covering the holes on your feet is to simply use lock cylinders in their place, which will also give you added security. You can use the Thule One-Key System # TH450400...

You will also need the Roof-Rack Foot Pack # TH710501 as well as the Fit Kit # TH145043. This will give you a weight capacity of 110 lbs although I recommend looking in your owner's manual to see if the roof weight capacity of your 2017 Honda Civic will be the limiting factor or not.

The Canyon XT has a 150 pound weight capacity and will allow you to fully open your rear hatch on your vehicle while installed. For extra security, I recommend the One-Key System Lock Cylinders # TH450400. Also, if you need straps to secure your cargo, I recommend the Rhino-Rack Cam Buckle Cinch Straps # RRRTD35P.
