The locking plugs are designed to work with an interlocking receptacle. They are manufactured from corrosion resistant marine grade materials. An interconnecting system securely locks the plugs into the receptacle resulting in a positive and moisture proof connection. Perfect for boats and ATVs, which vibrate and bounce due to rough water and bumpy terrain. Simply line up the tabs on the locking plug with the arrows on the receptacle and press the plug into the receptacle until it seats. The plug is locked into place. To remove the plug, just rotate it 20 degrees and pull out. The plug features a moisture proof sealing ring and cord seal, interchangeable 3 amp fuse, and a green LED which indicates power. You must slide the rubber ring off towards the front, unscrew the tip and remove the Phillips screw to install the wires.

Both plug and receptacle will work with any standard 12V equipment, however the locking system will only work when locking plugs and receptacles are used together.
