Electrical box with main cavity and separate auxiliary cavity and having optional dimpled hole and strengthening element

摘要

Mounting assembly includes a junction box having a top wall and a side wall. The side wall extends downwardly away from the top wall and defines a cavity therein. An auxiliary cavity may be provided adjacent to and outside of the cavity. A support may be provided that is at least partially within the auxiliary cavity. A dimpled hole may be provided in the top wall, and the supplemental fixture support extends into the dimpled hole for engaging at least a portion of the walls thereof. A threaded hole may be provided on the supplemental fixture support. The supplemental fixture support may be a stud or rivet. A rough surface or fluting may be provided on a portion of said support for engaging the walls of the dimpled hole. Preferably, the supplemental fixture support has exposed portions which are sufficiently smooth for preventing wear to plastic-coated electrical wire which engages such exposed surfaces of the fixture support.
