Visitor Bell Trio A trio of bells, each with three internal clappers, create a delightful harmony of differing bell chimes. The bell includes a pull chain, allowing it to be used as a service bell or doorbell when mounted to a stationary surface. The bell may also be mounted to shop doors or gates to create a lovely sound when moved. Each bell is cast in solid brass and mounted to powder-coated steel for use indoors or outdoors. Center bell measures 2.5" diameter, side bells measure 2.25" diameter. Mounts with 2 screws (included). Made in Connecticut by America's oldest surviving bell maker. » Click here to listen to the Bell Trio Please Note : Brass is a hard metal alloy of copper and zinc. When used outdoors, brass will gain a darker patina over time. However, brass does not corrode and is safe for all outdoor environments. Although fully powder-coated for endurance, steel is a naturally changing element that may gain a patina over the years. However, the bell tone and function will remain unchanged. ~ Made in the USA ~ overall size: 8.25" wide x 5.25" high x 5.25" deep; pull chain is 8" bell size: 2.25" side bells and 2.5" center bell weight: 1.5 lbs. materials: cast brass + powder-coated steel
