Replacement Mounting Hardware for Thule Adventurer Rooftop Cargo Box


Hello. I have a Thule Adventurer rooftop box which affixes to the Thule bars with a u-shaped bolt. Unfortunately we have lost one of these bolts. They look similar to your Thule part 43216, but the size is different. My bolt is approximately 2 1/4inch from outside edge to outside edge, with the space between the bolt ends of just under 1 3/4. Do you have a replacement for this bolt? I am happy to send a picture if that would be helpful. Thank you.

We do offer the replacement mounting hardware for the Thule Adventurer Rooftop Cargo Box, however the Adventurer was not designed to use U-bolts to mount to the crossbars.

The mounting hardware that will replace the original mounting hardware for the Adventurer cargo box is the Replacement QM3, Quick Mount Hardware, for Adventurer Cargo Box # TH04997. The QM3 uses carriage bolts in conjunction with the Quick-Mount brackets to secure the cargo box to the roof rack. This is the hardware Thule recommends for mounting your Adventurer cargo box.

Since the Adventurer did not originally come with a U-bolt for mounting and is not the recommended mounting hardware, Thule does not offer a replacement U-bolt in the size you described.
