  • Universal central vacuum cleaner hose end fitting
    Patent number: 5387117
    Abstract: A "universal" end fitting for a central vacuum cleaner hose, having a reversible electrical connector body that can be reversed without being disconnected from the end fitting, and which accordingly need not be realigned after being reversed, is provided. The connector body is permanently but rotatably affixed to the end fitting. Because it is permanently affixed, the connector body need not be realigned after being rotated to a new position.
