Boatside connector features a molded-in LED power indicator light. When it glows red, you know you have power to the boat. Both plug and connector ends are molded to fit the contour of your hand. When the thumb-print is in the 12 o’clock position, the blades line up for easy connection. Easy Lock™ system quickly locks the cord set to the inlet in just 1/8 of a turn. The exclusive locking tabs engage slots built into all Marinco inlets. 5 year warranty.
