Abstract: An Ethernet surge protector can be mounted externally and/or internally to a wall of a building. The Ethernet surge protection device may include a housing, a threaded port, and a surge filter. The housing may define a space along an axis. The threaded port may be configured to be coupled to the housing, and it may have a locking surface that may be configured to prevent the housing from rotating about the axis upon engaging a mounting fixture. The surge filter may be disposed within the space, and it may be configured to filter out a surge component of an Ethernet signal received from an input cable.
