The sprocket and chain are made from hardened steel to provide years of continuous operation. An acetal case liner keeps the chain and sprocket sliding smoothly. The high-pressure, zinc die-cast case is phosphate coated, electrostatically painted to provide a finish that resists chipping while maintaining color stability for years in direct sunlight.
