Please see dims in the pictures. This part was cast from an original German made footman loop used on a Volkswagen Westfalia Camper Bus. (for the child's cot or roof mounts)
It could be used for any application though.
Very high quality. Made by a company that makes stainless parts for yachts.
Price is each. Shipping is a fixed $5 in the USA no matter how many you buy. Email be for international.
