ABSTRACT

Presented are multipiece, surface-mount electrical boxes, methods for
making/using such electrical boxes, and electrical systems equipped with such
electrical boxes. A representative electrical box is a bipartite assembly that
includes a backplate and a faceplate. The backplate includes a planar body
that seats against a load-bearing support surface, such as an exterior face of
a building wall. The faceplate includes a dome-shaped central hub with a
mounting flange that projects outward from the central hub and mounts to the
support surface. The mounting flange includes a recessed backstop that
receives therein and surrounds the backplate. A set of flexible press-fit tabs
may project from the backplate's planar body such that the backplate is
slidably received in the recessed backstop and the press-fit tabs interference
fit with the interior walls of the recessed backstop. The backplate and
faceplate may each be integrally formed from a polymeric material as a
single-piece structure.
