The finish closely resembles the color of a Satin Chrome (26D) finish lock.
We recommend the Marine Grade Finish for saltwater environments where the lock will sustain consistent exposure to the elements.
It has a much longer lifetime than a standard finish and provides added strength against the corrosive elements of coastal/saltwater environments.
