Marinco 30 Amp Right Angle Cordset Adapter #1RPC. The Marinco Right Angle Cord Adapter allows you to convert an existing 30A power cord from a straight connection to a right angle one, providing more clearance in tight spaces. The GripLock handle design makes it so easy to hook the cord up to the adapter that it can even be done in darkness. Each adapter is constructed with a super flexible 10/3 cable and includes both a threaded and EasyLock ring. A sealing collar provides additional protection of the connector and cordset from the damaging effects of moisture.
