Fits very well as intended. Its about a 99% exact fit for my load bearing roof rack bars.


I'm so glad you had these clamps! They were hard to find!


Awesome. These also fit the Universal Square Bar Adapter, which is designed to clamp onto any crossbar or raised rail roof rack, the allow you to mount Thule square crossbars to whatever style rack you may have.


Works as intended and allowed me to get my legacy Thule rack system back up.


I very much like the low profile and slim line look of these mounts. I installed them on pickup truck bed ski rack.


I needed specific replacement parts for a Thule bicycle roof rack. The process to find the parts could not have been easier on the eTrailer web site. I simply searched using the Thule part number and immediately found what I needed. After submitting my order, I discovered that I needed to update my order. The customer service representative was extremely helpful and friendly. There is no need to look any further for your trailer and rack needs. eTrailer is the best.


Works great with attaching my older style fairing to my Thule 444 roof rack. Thule states that the mounts for the 555 fairing are no longer available but if you use this and a M6 square head bolt and an M6 3-wing hand knob they work like a charm for securing the fairing!

Did you also purchase the M6 square-head and 3-wing knob from here? If so, would you mind sending me a link for them? Possibly the part ? Thank you!

This part fit my application perfectly... This helped me attach my Thule ski rack to a round cross bar. The original mount that came with rack was for oval bar. Thanks etrailer customer service for helping me solve my problem...


Bought these as replacements for cracked and aging mounting hardware for my existing ski racks. Everything came exactly as ordered and fit great on my roof racks. Price with shipping was less than buying directly through Thule! It was really helpful to be able to shop by Thule part number. I actually found this site by googling the part numbers I needed.


I bought these to retrofit my Thule SquareBars for a bike rack that I already had. This part works perfectly with a 6mm carriage bolt to create an attachment point on the SquareBar for just about anything you want to mount!


While this is a perfect replacement for the thule piece I had that rusted out ( after about 10 years) . I've found that this one has started to rust out in just a year.
It is the ONLY replacement I've found, and at a great price, so it works great.
If need be , I'll be buying all new ones next year.
( as you can see the other parts are rusting as well,,, but same goes.. only replacement I could find.. so I'll buy those in a year also )

by: is by far the best source for Thule parts and pieces! I searched online for weeks for the right parts, for the right price, and I found EVERYTHING i needed and more at! Their shipping costs were very cheap and the parts arrived quickly. I kept adding more and more to my order because I found so much great stuff here for an AMAZING price! has a new customer for life! Service was excellent, and they took care of all my needs immediately! I even had to change my order 2 times and it was SO easy to work with their customer service staff! I cannot say enough good about my experience ordering from Truly a PERFECT online shopping experience in every way! THANK YOU!


Perfect fit, old one snapped when putting it on this year, these came fast an exactly what I needed


Great replacement parts for Thule racks. Ordering was easy and product arrived in a short amount of time.


Tough to find part that was necessary to use my Thule ski rack that had clips for my old Jeep. etrailer mailed it same day and arrived 2 days later. Great experience.


A quick and inexpensive solution to a failed part due to age/weather. These clips allow me to maintain my Thule rack without an expensive purchase! Thanks again etrailer!


Product fits perfectly on thule square racks plastic feels a little thinner than original but time will tell......very fast w/shipping


Great service. Had the replacement part I was looking for for my older model rack and shipped out quickly and at a good price. I'll definitely shop here again!

Still works good thanks.

One of clips on my Thule ski rack broke, I was thrilled to find a replacement at such a reasonable price. The clipped shipped quickly and the clips were exactly as shown.
Highly recommend!


Looks to be of the same quality as my Thule adapters for much less. Order process was simple and smooth from start to delivery. very satisfied.


Replacement parts fit and worked well.

We are pleased to hear you’re happy with your purchase.

  • Replacement Mounting Hardware for an Older Thule Flat Top Ski Carrier
    For the factory roof rack on your vehicle and the Thule Flat Top ski carrier you will actually need Universal Mounting Kit, # 7533998. This kit was designed exactly for what you need; attaching the carrier to a factory rack. You can get replacement keys. I would need to know the number on the face of the lock to recommend the correct key.

  • Best Option to Upgrade a Thule 597 Ski Rack
    I have a solution but unfortunately there is not an adapter available for the Thule 597 Ski Rack carriers to work with aero bars. Your best bet is to upgrade your ski carrier to a new one that is similar. The Rhino-Rack Ski and Snowboard Carrier - Locking - 4 Pairs of Skis or 2 Boards item # RR574 is the most comparable option that will fit your Yakima CoreBars.

  • Adapter Recommendation to Fit a Thule Flat Top Ski Carrier on Aero Bars
    Thanks for the pictures! Based on that it looks like you have a Thule Flat Top and need the part # 7533998 to allow it to fit aero bars. Your other option is the Thule Ride-On Adapter part # TH532 which will also fit your bars and provide you with a square crossbar.

  • Replacement Mounting Hardware For Ski Carrier On 2015 Subaru WRX
    The ski rack you have sure looks like the Thule ski racks we offer. The replacement adapter we offer is the # 853-2156 that attaches to the crossbars. You may need a couple of the other parts to complete the installation. You may need the washer, part # 853-2154, and the carriage bolt, part # 915-0625-54, as well as the nut to hold it in place, part # 936060054.

  • Solar Panel Charging System Compatibility On a Tear Drop Trailer With Thule Square Bar Roof Rack
    I recommend using the Go Power Solar Flex Charging System with Digital Solar Controller # 34272628 on your tear trailer. These solar panels are flexible and will follow the curve of your roof line. This particular kit has 2-100watt panels for a total of 200watts of power. Each panel is 44-5/8" long x 21-7/16" wide x 1/16" deep allowing you to not have to mounts a rigid panel to your rack. If you go with a ridged panel setup like the Go Power Overlander Solar Charging System # 34282181...

  • Replacement Parts for Thule FlatTop Rooftop Ski and Snowboard Rack
    I do recommend picking up the entire replacement kit, part # 7533998 and putting it into a small kit you can carry with your other roof rack supplies in a small bag like part # PW2 , just for preparedness' sake, but, the individual part numbers for what you're looking for are: Rectangular Washer (1pc) - part # 853-2154 M6 x 50 Carriage Bolt (1pc) - part # 915-0650-54 2-Wing Knob (1pc) - part # 753-1897-03 Clamp-On (Square Bracket, 1pc) - part # 853-2156

  • Replacement Clamps for Older Thule Ski Racks
    This will depend on the specific model you have. If you have the older PullTop Deluxe (Made between 2000 and 2006), or Flat Top (made between 1996 and 2006), you'll want part # 853-2156. These are easily identifiable as they have either a square clamp-on box or no attached parts on the bottom of the carrier. If you're missing the carriage bolt, you'll need part # 915-0650-54 to replace it. You can also convert this kit to a Universal Mount with the required parts for newer, post 2006...

  • Adapting Old Yakima and Thule Roof Bike Racks for Aero Factory Crossbars
    It depends on your bike mount and brand. Yakima has their Universal Mighty Mounts # Y03590 that should help with most of your Yakima carriers. Thule has their Xadapt series: # Xadapt1 and # Xadapt2 for crossbars that have a t-track in them. If not, they have this old Ride-On Adapter that is now only available in its individual parts: 4 of the # 915-0625-54 4 of the # 853-2154 4 of the # 853-2156 4 of the # 853-5267 4 of the # 753-2854 4 of the # 936060054 4 of the # 853-5269 8 of the...
