This is a set of square-type roof bars and bar end hooks from the RV-INNO series by Car Mate. I used them on an RV about 15 years ago, but removed them when I changed vehicles and stored them in the warehouse, thinking I might use them again someday. The total length is 107cm. With the bar end hooks attached, it extends to approximately 30cm longer. I recall that due to strength and traffic law considerations, it was not possible to drive with the hooks extended. Although the model numbers are different due to the age of the product, they are equivalent to the current models: Square Bar INB107BK and Bar End Hook IN551-6.
