Average Customer Rating:  4.8 out of 5 stars   (69 Customer Reviews)

This clamp-on fits around a square Thule load bar to provide an attachment point for the mounting clamps of your Thule Ride-On adapter. Clamp-on attaches to mounting clamp with carriage bolt, rectangular washer and hex nut (sold separately).


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


Service was excellent and the part did what I needed it to do. Very happy.


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!

Patrick B.


He sure did. I pulled open his order and the bolts he used are 853-208909 and the 3-wing knob are 753-0783. Links to the parts are below.


They were a good match to the originals, fit correctly and seem to be sturdy.

Waaaayyyy cheaper than buying a replacement from Thule.


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.


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 )


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!

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!


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.


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...


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.


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!


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


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


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!

Brian C.


Still works good thanks.


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!


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


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


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.

Chris Y.


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


Great product , allows me to customize my rack and roll trailer!


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


The product is exactly as described. Delivery was fast as well which was nice.


These guys carry good selection of spares and adaptors for Thule. Store outlets and Thule web are a waste of time

  • 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.

  • Availability of Thule Square Cross Bar Adapter for Thule Fairings for Roof Racks
    I do believe we have the part you are looking for. Check out the Thule Square Bar Adapter for Fairing, # 853-7362. This adapter fits square crossbars and is for use with Thule fairings.

  • Does Thule Hullavator Pro Kayak Carrier Mount to Square Crossbars
    Those adapters will not work with the Thule Hullavator Pro Kayak Carrier and Lift Assist # TH898, but you also won't need them. The reason for that is the Hullavator Pro # TH898 will fit directly on your square crossbars, so no type of adapter is needed.

  • Bike Rack Recommendation to fit Thule Square Crossbars
    The square Thule crossbars are easily used with roof rack mounted bike racks. To see a full list of all the bike racks that fit square crossbars check out the link I attached. A very popular option that allows you to keep the front wheel on your bike is the Thule ProRide part # TH598004 which is a great option.

  • 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.

  • Replacement For Thule Hydro Glide Kayak Carrier For Aero Bars
    Thank you so much for the photo it was very helpful, and what it shows is that you have an older Thule Hydro Glide kayak carrier. This is for square bars only, and there isn't an adapter for this particular carrier that will allow it to be used on aero bars. The reason for that is it has been discontinued right about 20 or so years now and there just isn't enough of them out there for an adapter to be made for this carrier. So while I know it isn't the exact solution you were looking...

  • Replacement Clamp to Use Thule Ride-On Adapter On Factory Aero Crossbars
    The Replacement Top Mounting Clamp part # 853-5267 and Replacement Bottom Mounting Clamp part # 753-2854 are the best option for attaching a Thule Ride-On Adapter to aero factory crossbars. They will work with any aero bar up to 4" wide but there isn't a clamp specific to any one factory crossbar brand.

  • Roof Rack Feet for 2018 Chevy Equinox for Thule Crossbars
    If you have aero style Thule crossbars you could install them on the raised rails of your 2018 Chevy Equinox with the feet kit # TH710401 but if what you have is the square bars there won't be a current foot kit that will work with them since Thule has changed their square bar design and they now attach to a channel on the bottom of the bar. Only exception would be that Inno makes square roof racks that use exact same dimensions as the old Thule bars so you could use the feet # INFR.

  • Aero Bar Roof Rack Solution for 2019 Hyundai Kona
    Since Thule changed their square bars and roof rack feet there isn't a way to use your older style of Thule square bar on your 2019 Hyundai Kona. Your best option would be an all new roof rack like the Rhino Rack part # RR23QJ which attaches directly to your flush bars and gives you an aero bar rack that will be very quiet.

  • 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.

  • Replacement For Old Thule Flat Top Ski Rack
    I can certainly understand not wanting a whole new set up, but I checked with Thule and there are no longer replacement parts for this rack available, so a new ski rack is going to be your only option, but that doesn't mean you have to break the bank. Rhino-Rack makes really good racks at a lesser cost than their competitors but you aren't losing any quality. I recommend checking out (depending on how many skis you need to hold) the Rhino-Rack Ski and Snowboard Carrier - Locking - 4 Skis...

  • Aero Bar Roof Rack System With Gutter Feet For A 2021 Jeep Rubicon With One Touch Sun Roof
    If you want to use the Rapid Gutter Feet # TH65BJ on your 2021 Jeep Wrangler Unlimited, you can use them with the aero crossbars # TH711520 no problem! These feet are 5 inches tall so you don't have to worry about it interfering with your One Touch Sun Roof. It'll give you about 2-1/2" of roof clearance. If you need more you can go with the taller gutter feet.

  • 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...
