In a sea of traditional brass door knockers, the nickel, silver, and chrome Crab Door Knocker definitely stands out among the rest! This door knocker conjures up images of fisherman hauling up a plentiful catch. The Crab Door Knocker is designed by the metal crafter Michael Healy, and his skill is seen in the realistic detail of this door knocker, which is just as much a sculptural piece as it is a functional accent for your door. The Crab Door knocker is cast in a solid nickel, silver and chrome alloy. The surface is hand finished, polished to a balanced shine, and sealed with a protective coating.
