Bells are anodized aluminum, weatherproof, UV resistant. Clappers are wooden, weatherized steel, copper or aluminum, and may include chains or plexiglass. All hardware for mounting or hanging is weatherized.

"Bells 3" includes a stutter clapper, which provides more impacts to compensate for lower resonance of thinner-walled bells. Its larger bell has a wooden-tipped clapper, producing a softer and only slightly quieter sound. Tips may be broken off in favor of the sharper sound of the metal stem.

Raw aluminum.
