NEPTUNE® CHAIN
NEPTUNE® chain resists corrosion when exposed to harsh outdoor environments, including seawater. The exclusive NEPTUNE surface treatment process gives the chain its unique matte grey color and provides a protective finish that is more corrosion resistant than Nickel-Plated chains. NEPTUNE chain has the same high maximum allowable load as our standard carbon steel roller chain.
