The Pool Tool Zinc Anode [Light] (104F) is designed to help protect compatible pool light assemblies and surrounding metal components from galvanic corrosion. Lights, niches, screws, and bonding-related hardware can be exposed to challenging pool water conditions, especially in saltwater environments. This sacrificial zinc anode helps provide another point of protection by attracting corrosion before it reaches more expensive equipment parts.Use this light zinc anode when servicing pool lights, replacing corrosion-control components, or addressing installations where metal light parts show early wear. It is a useful addition to routine pool maintenance when corrosion prevention is a priority. Confirm compatibility with the light assembly and follow proper electrical and bonding practices during installation. Pool Tool part 104F for pool light protection Helps reduce galvanic corrosion around compatible light assemblies Useful when servicing lights, niches, and related hardware Supports saltwater pool corrosion-control maintenance Designed for professional and homeowner repair needs
