The Nucli-eye ® Eye Socket allows a Cordless Extreme to be mounted to a relatively flat surface on the Gunnel of a boat. The receptacle comes with 16 ga multi-stranded wires (approximately 18”long) attached to a ¼” RCA monaural receptacle. It includes a 14 ga 304 SS face plate to cover the hole. A full sized drilling template is included. The Eye Socket is open and will drain to prevent contact corrosion. A plastic button is furnished with each Eye Socket to keep excess water out while boating without using the Cordless Extreme.
