This is a spare part removed from a roof rack carrier base. I've forgotten the manufacturer. Would anyone who recognizes it from the photos be interested? I'm a novice, but I believe there are no cracks or splits in the plastic parts. The screw part was about 30mm long. Please understand that these are used parts. Please refrain from purchasing if you are overly concerned about condition. Shipping will be in simple packaging. ⚠︎ The following description was generated by AI. It may be incorrect.
