These door knockers are substantial – easily recognized from a distance and interesting in detail up close. Each piece is sand cast in solid yellow or red brass, hand finished, assembled and lacquered for tarnish resistance. Various color patinas and nickel plating can also be applied to any design. Mounting hardware is provided for use on wood, metal or fiberglass/composite doors. If ever needed, Colby will completely refinish his door knockers for a small fee.
