Question:

Hello, I purchased a trailer which already has a rhino rack installed, and I am unsure of the exact model. Ive been trying to mount an awning, but cant find the correct bolt for the track. I believe the RR52XB will work. Can you please confirm the dimension of the Head? Length and Width appear the same, but Im also curious about thickness. Thank you, Greg

Hey Greg, thanks for reaching out. I ran out to our warehouse and measured one of the Replacement M8 x 30 mm Square Head Set Screw for Rhino-Rack Accessories # RR52XB. The head of the bolt is 0.8" x 0.8" and 0.1" thick.

They should be compatible with most Rhino Rack tracks and top channels.

Are your Rhino crossbars aero bars? Or a different shape?
