The 50 amp non-metallic inlet offers superior performance and ease of use. The streamlined design includes all of the same high quality electrical components as our stainless inlet products. Multi-Point Locking System - Side clips lock the plug securely into the inlet which eliminates any stress on the pins from movement of the power cord. Weatherproof Seals - Multi-fin silicone gaskets installed in the inlet cover & interior of the plug body eliminates moisture penetration. Quick & Easy Installation - Inlet mounting flange holes match twist-type holes for an installation that is typically finished in 30 minutes. | Smartplug Systems LLC 50 Amp 125/250V Non-Metallic Inlet, White
