SO GLAD etrailer.com carried this part! Couldn't get it on the Thule website even though the bike trailer was only a few years old. It fell off at some point when the bolt came loose. This replacement is identical, fit perfectly - YAY! Thanks, people!! 425099

Received my good well packed and fast... I had a pair of Thule 510 Tour on my old Saab but when it decided to bite the dust... I took them off in hope transfer them into the new commuter a Volvo V40. I misplaced these T bolts and needed replacement (along other bits and pieces) and etrailer.com carries most of Thule's part and I was able to repair and/or modify most of old Thule's system... thanks and always a pleasure to deal with. 389589

Good replacement parts! I bought a used Thule big mouth roof rack that was missing parts and etrailer had just what I needed and was very helpful! The parts seem to be holding up quite well after one year of use too. I will be back if and when I meed more parts! 639300

These guys were great. The website was well laid out and it was easy to navigate to the products that I needed. I ordered it on Saturday and they called me on Sunday to clarify my shipping address. I am impressed people are working on a Sunday and they phoned to clarify. That goes above and beyond most places. The email updates when the package was shipped were much appreciated. Plus I received my package quite quickly. All this for a $ [minimall] total order. I ordered Thule replacement bolts and bits and I am just glad I could find them and make this transaction as painless as possible. Thanks to everyone who works there. 414062

I ordered several parts from etrailer which I had struggled to find at local retail stores and other websites. etrailer had the parts I needed and they were in stock. Shipping was prompt and on time. The order I received was complete and all the parts were exactly as advertised. I would highly recommend etrailer to anyone who is looking for rack and towing equipment and hard to find accessories. 106112

No issues w/ the product, exactly as shown, worked great. etrailer unfortunately shipped the product a day after they had said they would. I was hoping they would make up for their mistake by shipping it faster (so it would still arrive when they had originally said it would), but they did not. If your order isn't time-sensitive, then it'd be no concern, but don't rely on their shipping speed. 95758

We do offer a longer Thule T-Bolt, part # 853-6511, which measures 3-1/2 inches long and 7/32 inches diameter. We have a variety of replacement hardware for various brands and products but since I do not know the specific Rhino rack you are trying to install, your best bet...

  • Recommended Spare Tire Holder and Bike Rack For Rola Roof Basket
    If you have the Rola Roof Mounted Cargo Basket # 59504, there is not a spare tire carrier that is designed to fit. There are a couple of possible options with a little ingenuity like the Spare Tire Carrier for Rhino-Rack Alloy Tray Roof Cargo Carrier # RSWH or the Spare Tire Carrier for Yakima Roof Rack Cargo Baskets # Y07076. In order for a bike rack to be compatible, you would need to add the Rola Roof Mounted Cargo Basket Extension # 59505 to give you the additional 18-3/4 inches....

  • What are the Dimensions of the Replacement T-Bolt for Thule Roof Rack Gutter Feet
