I have a very old but faithful Thule roof rack. One of the tightening knobs gave up. I was able to find exactly the replacement item I needed. Thanks Easy to use website with lightning fast shipping. My paddle partner sends her thanks as well.


Very quick delivery. Excellent replacement product.

Awesome product! Nice improvements compared to previous version.

I love the smoothness of the lock set and locking knob for gutter-mount racks. As it turns out, I didn't need the knob, just a new lock set. I'm happy regardless as it looks much newer than the others on the car. Probably going to order another to keep a nice matching set on the side of the car. My preferred method of removal for the lock plug is to take the three screws out on the back of the knob and tap it out using a punch and small hammer. Another good way is to use a large pair of wire strippers, with the flat side against the knob and the angled side (the physical stripping part of the pliers) under the plug flange. Gently wiggle up and down on the strippers and it will remove the plug evenly and without chipping the sides.Couldn't beat the prices and shipping was very fast. Thanks, etrailer!

Its been a year since I installed my new knobs and locks, they still work fantastic and never give me any grief. Looking forward to another year of service!

The product I ordered was reasonably priced, came 3 days before I expected. The ordering process was easy and the website well put together. Great service!!! Thank you!!!


My only complaint is that Thule does not make known how this knob attaches to the rack. Other than that service is excellent and quick. You get what you order and they are quality parts.

With additional hardware you can adapt it to work

I wanted to replace my regular knobs on the arms of my Thule bike rack with lockable ones. I already had one extra knob but needed another. When I searched the web I found that there were 2 kinds. One was a cheap imitation with plastic threads and the other was the real deal - a Thule replacement part. etrailer had multiple images of what I was looking for so I was certain I was going to be getting a Thule knob with the metal threaded core and at a very reasonable price to boot.

I also needed a lock cylinder that would not only fit the knob but one that was keyed to the other knobs I had and etrailer had it. It was very convenient to be able to purchase both items from the same place and on top of it all I received the items faster than I expected.

The reason why it was important to get a knob with a metal core is because I needed to access the inside of the knob and exchange the nut it comes with with one that had a different thread and matched my bolts. Now I can not only lock the rack to the rear mounted spare on my Wrangler, but I can also lock the adjustable arms to prevent them from being stolen - all using the same key.


Wow. This was exactly what I needed. It is a perfect replacement for the original knob from my 30-year old roof rack. The threads on the original knob were stripped. This one fit perfectly and I was able to insert the old lock into the new one. I did have some difficulty removing the plastic plug from the new knob and had to disassemble the knob it and force the plug out from the inside. A minor inconvenience for a replacement knob that is priced so reasonably. Thanks to etrailer for keeping these old parts available and giving years of life to old bike racks.


The locking Nut on my Thule Canoe Rack would not tighten. I found the exact locking Nut I needed at It was easy to order and worked perfectly on my Thule Canoe Rack when received. I was very happy with my experience at


The exact product and worked perfectly with my Thule 9025 bike rack carrier. Have recently purchased multiple replacement items and highly recommend etrailer. Great prices and multiple shipping options m


This was the second or third time I’ve ordered from etrailer. The first orders were for replacement parts on a 20 year-old boat trailer. All parts fit and operate as expected. The staff at etrailer is very helpful, filling orders quickly and accurately. Their prices are very competitive as well. I definitely recommend etrailer.


Needed to replace a damaged knob and it was a perfect "OEM" replacement.


Direct replacement for my thule rain gutter foot pack on my 2016 Jeep Wrangler. Fit perfectly, just what I needed. I needed to replace one of the knobs I stripped overtightening.


These are the weak link in the canoe rack that mounts on the rain gutters on a Jeep. This is the second time I’ve ordered replacements. The plastic part strips easily when tightened.
etrailer Corp is great! Fast service. If your going to get these racks, etrailer will have the parts you will need to keep it secure. Just my experience.


Excellent service great replacement par ts


Typical excellent quality from Thule. Easy to install.


Great locks for the window gutter rack. I used the old screw hardware from my old non-locking piece to put on the new locking piece. Works great


Great product, works great on the rack. Would order again, for sure!


This was just the knob i needed to repalce a broken one on my existing rack set up. Shipping was fast, easy to track, and the packing was simple, and environmental friendly by using paper wrapping and a combined label/ packing list sticker.


For all in search of a quality item and service This is the place!
Order with confidence!


Product was priced well, service was excellent. Fast shipping reached me on the road during an extended trip (I would say "without a hitch", except that their fast shipment meant I still had use of one!) Thanks.


Etrailer is very fast with shipping, great on prices and you get exactly what you order! Will shop with them again!


etrailer is so easy to navigate. I even searched the manufacturer's site and it was so hard to find what I needed. I bought from etrailer because the price was reasonable, but more significantly because it was easy to find.


As expected and in time for my trip. Etrailer is everything that is good about buying online.


The product was exactly as described. I had purchased locks for the knobs locally, and they installed easily and fit perfect. Delivery time was also faster than I expected.


delivered exactly as said - part worked great! thank you etrailer!

  • How to Install Locking Knob On Thule Apex When Original Knob Is Broken
    Typically the lock will need to be in the unlocked position in order to unscrew the Locking Anti-Rattle Knob for Thule Apex Bike Racks and Rain Gutter Foot Packs - Qty 1 # 753-0073 from the locking hitch pin. If your lock was in the locked position before the knob was broken off, you'll likely want to try to start with unscrewing the gear shaped washer and seeing if that allows the knob to turn freely on the bolt. You also may want to take a thick flat head screw driver for the head of...

  • Can Lock Cores from an Older Thule Roof Rack be Used in a New Thule Roof Rack
    Yes you can remove the lock cores of your old Thule roof rack and use them in your new one. All you need to do is have the lock cores in the unlocked position and then insert the change key part # 853-1251 and they will release from the rack so that you can slide them out and install them in your new rack.

  • Replacement Lockable Knob for Thule Super High Gutter Feet
    The knob that you need for your Super High gutter feet is actually # 753-0073. As it comes the knob does not have a lock core in it (which is something that Thule does in case you have other Thule products with locks. It allows you to purchase a lock that matches the others you may have). To add a lock you can get # TH450200 which is a 2-pack of locks, 2 matching keys, and the change key needed to install the locks.

  • Replacement Locking Knob for Thule Raceway Trunk Mounted Bike Rack
    Since the knobs stopped working on your Thule Raceway # TH9003PRO it sounds like they need replaced and not just the locks. You will use the Replacement Locking Knob for Thule Trunk Mount Racks # 753-1909 which will give you the integrated lock. If the knobs were working properly you could remove the lock and they would still allow you to close the clamps.

  • Troubleshooting Anti-Rattle Feature Not Working on Thule Apex Bike Rack
    Since the tightening knob for your Thule Apex 9026 bike rack (replaced by the Apex XT # TH9026XT) is spinning you want to first verify that the key is in the unlocked position. This bike rack had a neat feature where the knob would just free-spin when the key was in the locked position to help deter theft. If it is in the unlocked position then the next step would be to use the Locking Anti-Rattle Knob # 753-0073 and see if that fixes your issue. If you are still having issues with the...

  • Cannot Loosen Knob on the Thule Apex Swing 4 Bike Rack Part # TH9027
    The locking knob on your Thule Apex Swing 4 Bike Rack part # TH9027XT will be loose while it is locked and tight when it is unlocked. By tight, I mean there is a considerable amount of force needed to turn it so do not be afraid to roll up the sleeves and give it a few good hard turns. With that being said I believe there is just a bit of confusion as to when the knob is locked or not so it appears everything is in order but if this is not correct then please get back to me and I will provide...

  • Locking Knob Installation For Thule Apex XT 4 Bike Rack
    The Replacement Locking Anti-Rattle Knob # 753-0073 will simply screw on to the anti-rattle hitch pin at the base of the rack. If you have a Thule Lock core you'll need to make sure it is in the unlocked position in order to install the knob-this is an anti-theft feature that prevents the knob from being engaged when locked. If you need a lock core like the Replacement Lock Cylinder # THLOCKN070 you can use this to keep your Thule Apex 4 XT # TH9025XT secure.

    I spoke to my contact at Thule about a locking knob for your Thule Pro 559 bike rack. The locking knob you will want for your bike rack is # 753-0073. This knob does not come with a lock core. If the existing lock core on your rack is a N series lock, meaning the lock number begins with an N and is followed by 3 digits, you can use a Thule Universal Change Key # 853-1251 to remove the lock core from the existing knob and place it in the replacement knob.
