Info & Guides

The EEL System Explained

Maintaining watertight, consistent shore power connections is critical for the integrity of your boat's electrical systems as well as your safety. Cordsets and plugs have traditionally depended on locking rings that can break or become cross threaded.

EEL stands for Easily Engaged Lock. It clamps down to lock plugs in place. Built in indicator lights show whether you are still plugged and whether power is flowing. Universal fit with all inlets.
