Accessories
- Generac offers fascia base kits or base plugs for air-cooled home standby units up to 26kW. These keep unwanted rodents and debris from entering the underside of your generator.
- Fascia kits and base plugs are not available for the CorePower or PowerPact.
- Paint is also a protectant against corrosion. Generac offers touch-up paint in tan, bisque, and gray, which not only keeps your home standby generator looking new but also protects it from rust.
