SmartPlug Data Ports are the perfect complement to our stainless steel shore power inlets, offering the same appearance and high-quality marine-grade stainless steel construction. They feature a weatherproof seal that uses a closed-cell foam gasket in the inlet lid to help keep out moisture. The ports also provide ease of use by locking securely into the edge of the SmartPlug mounting flange. Installation is simple, requiring only four screws to mount, and each unit includes a silicone mounting gasket, eliminating the need for messy caulk.
