ABSTRACT:
An enclosure with a tubular coupling; for containing electronic components, circuits, and other components. The tubular coupling may provide both a support means for the enclosure, as well as a raceway for connecting external wiring. The enclosure is optimized for surface-mounting to an existing larger enclosure, utilizing a single hole in the wall of the larger enclosure. The single hole may be the size and shape of a standard electrical conduit knockout. The hole may be made with a standard hole punch intended for making holes in electrical enclosures for electrical conduits. The tubular coupling fits into the hole, and the inventive enclosure may be secured to the larger enclosure with a threaded nut (with a threaded tubular coupling), a retaining clip (with a notched tubular coupling), or other suitable hardware.
