Park Power -S30-15RV One-Piece Adapter with 30A Locking Male Plug and 15/20A Straight Blade Female Connector

One-Piece Adapters are high-quality, one-piece adapters similar in usage to Pigtail Adapters.

However, they do not have sealing collars and are not recommended for use in wet locations. Use only in an enclosed, dry location, such as powering your RV from a 15A power receptacle inside your house.
