A reversible electrical box assembly for mounting an electrical fixture on
a ceiling. The electrical box assembly includes a hollow body having a
sidewall. The sidewall includes two ends and a center. A flange extends
outwards from the sidewall at a location offset from the center thereby
dividing the sidewall into a long and short sidewall. A panel is provided
for closing either of the ends of the hollow body. The panel can be
secured to either the long sidewall or to the short sidewall to create an
opposing sidewall of an appropriate length for extending through the
ceiling covering at the job site.
