Cast from Solid Brass and come complete with a wall bracket which has two methods of mounting, as shown in the pictures.Each bell has its own quality rope lanyard, plaited for strength and visually attractive.As with all brass items they will require ongoing maintenance, especially with regards to the rope and clapper we recommend for longevity they are used with only moderate to low impact as even with limited force the sound level produce is considerable.The crown, shoulder and sound rim are manufactured from solid brass and will require no functional ongoing maintenance. Each one is coated in a stove lacquer, so we recommend when cleaning avoiding the use of harsh chemicals or substances which may remove this protective surface and cause the brass to tarnish.
