Using these Thule track nuts allow the Rhino Quick Mount legs to be mounted easily, without removing the end caps on the Thule Tracker II rails installed on our truck cap.

by: Jeff 06/04/2026

Exactly what I needed. Have an older thule set up that I've moved to/from a few vehicles. Lost these track nuts along the way and couldn't find them anywhere else. etrailer always comes through.

Awesome, Jeff! I'm glad we had the parts you needed!!

Installed on Thule Tracks on a Leer 122 camper shell. Fits well in the tracks. Can be installed without having to remove the end caps on the tracks.

Great product. Still fits well in the Thule tracks on my Leer 122.

by: Dan R. 09/13/2017

I just purchased a new camper shell and one of the optional equipment is the installation of Thule tracks. I already had Yakima cross bars, cargo carrier, ski racks, kayak racks, etc. Well these Thule track nuts fit perfectly onto to my Yakima foots and cross bars. You have saved me from buying a complete new rack system. Thanks again for very quick delivery (ordered on Monday and received on Wednesday). Thanks again.

Still great and super functional. The ease and f taking the racks on and off and the secure grip makes me worry free when using the rail system of my racks.

by: John A 09/05/2019

Excellent for attaching anything to factory tracks on camper shells. I used them to mount a Smittybilt Defender roof basket to my fiberglass Leer Commercial Cap (heavy duty).

by: CR 05/07/2025

Joshua was awesome. He sent me the parts quickly and they fit what I needed. Such a relief. I would have had a kayak rack I wouldn't have been able to use since the place I ordered it from wouldn't assist me with the missing hardware. Thank you Joshua.

by: Thomas 12/12/2021

This is the nut you need if you have a track with accessories attached that you don’t want to bother moving (which requires removing the rivet on the end cap and then reinstalling). With this nut you drop it in anywhere along the track in the narrow orientation and as you tighten it, the nute rotates 90 degrees in the track and locks into place in the wide orientation. I had Thule tracks on my van roof that were used to attach solar panels that I did not want to mess around with removing (it would have required removing end caps, detaching wiring, sliding them out the ends of the tracks, and then putting it all back together). I had Yakima towers and bars on back order and needed to cobble something together for a trip. I was able to order four of these nuts and picked up some M6 bolts at the hardware store to anchor a block of wood that I attached to a wood crossbar. When my Yakima towers arrived I took my temporary wooden rack off and installed the towers using the same nuts instead of the square nuts that came with my towers (this did require me to order 4 more of these nuts as each tower had two anchor points). This is a great product that opens up flexibility for anchoring either your own custom accessories or factory towers from either Thule or Yakima without having to slide the standard rectangular bolts the length of the entire track—you just drop the nut in where you want it.

by: Michael R. 06/05/2017

I had an extremely difficult time finding the parts I needed until I came across etrailer.com! I got exactly what I needed in a short amount of time and for a very good price. Thank you etrailer!

Just Perfect!

by: Jeffrey 07/09/2024

If you have Yakima Tracks on your Truck Camper Shell, these slide into any open space along the track. I used some M6 Lifting Eye Nuts to make some perfect mounting hooks for hanging my camp kitchen storage bag or vehicle side hanging table. I expect these will come in handy for anchor points for my canopy or string lights.

Thank you eTrailer for having such valuable information on your website. I impressed that there was information for the competing brand that this worked for me as well as people with Thule racks. Once again, eTrailer has saved the day, your website has so many difficult to find items, I greatly appreciate this website and resource.

by: Chris 03/10/2017

This product is very handy. I have a truck with a canopy that has roof rack rails that work with both Thule and Yakima racks. My Yakima rack uses the Landing Pads that have rectangular anchor nuts or plates that require removing the end piece and sliding the plates into the track. Unfortunately, the end pieces are screwed through the canopy with the holes waterproofed, making them difficult to remove and re-install. These Thule nuts fit the screws supplied by Yakima and allow installing the Yakima Landing Pads without removing the end pieces. Very Handy. Thanks.

by: Brian 03/21/2024 One Year Later

great product, especially when most track nuts require disassembly to install on track, this solves that problem. used on yakima hd cross bars

by: Mike 01/25/2019

Just what in needed they will fit Yakima tracks . This will allow you to use your old Yakima mounts on new Thule tracks. $8.00 beats the cost of a new set of racks. Be sure to price challenge as they are only $1.00 each on the Thule website

by: Paul 02/14/2023 One Year Later

This diagonal piece of metal fit in the roof rail of my truck cap. I was then able to screw a bracket to it. I was totally awed with how it performed mechanically. It was able to secure itself under the rail and in addition I was able to thread a screw into the threaded hole. Again, a phenomenal piece of engineering.

Product arrived in an expeditous manner and worked as expected.

Part's fit and function was spot on for what I needed. The shipping from etrailer left something to be desired. Part was in stock at time of ordering, order tracking confirms in stock. Order ships 9 days later by usps then arrives to me 8 days after that. 17 days turn around for in stock items, leaves room for improvement.

by: Scott 08/07/2019

These work on Yakima Tracks too. They allow you to drop it into the track without removing the end cap which is why I got them. Be sure to get the appropriate screw as the threaded hole is a different size than the Yakima ones. I ordered mine with regular shipping and it came in two days which was three days faster than was estimated!!

by: Dan W 08/15/2013

Thule TK1 replacement parts were great. Just like original brackets from manufactured store bought kit. Great customer service and very quick ordering and shipping. Great company to do business with.

by: Dcraig 01/25/2020

This was a very simple and very small order, but the team at etrailer gave the utmost attention when we had some shipping problems. "No order too small" is the TRUTH at etrailer.

It was my first order with etrailer, but I'll be back time and time again.

Etrailer had what I wanted and shipped it out the next day, great customer service sent me an email and tracking number and my order was delivered promptly, great price on my Thule parts.
Thx etrailer

by: Adam G 06/15/2016

I bought this as etrailer and Thule stated that for the 3101 footpack (which is the only current pack that you would use to mount Thule Podiums on their Top Track product) there were no replacement parts. On delivery and inspection, these are the exact same nuts that are used in the 3101 foot pack down to the micron.

by: Brian 08/16/2021

The product was spot on. But I thought that it was a package of 6 track nuts. I paid $[x.xx] + tax and $[x.xx] and only received 1 track nut. Probably my fault for not paying full attention but that’s pretty costly for basically 1 nut.
