What it does

Bring power through the wall cleanly.

PortPlugs create a cleaner exterior power pass-through than pinching extension cords through doors, vents, or gaskets.

Adds an exterior plug point for temporary power, battery chargers, block heaters, tools, or light-duty powered storage.

The snap-fit cap helps protect the connection point from snow, ice, freezing rain, and jobsite weather.

Designed around a 2 inch hole, four screws, and an integrated cord for a cleaner OEM-style result.
