Up for sale is a pair genuine Cadillac roof rail crossmembers. This accessory enables you to carry anything on your roof rack. cargo box, bicycles, surfboards, canoes,or anyhting else you feel like.
Rails are in excellent condition. They are only about 2yrs old.they come with a lock on everyside so noone can steal them.

They probably could fit other gm vehicles but you would have to check dealer for this.

They are made by THULE for GM. I bought them brand new from Conte Cadillac
