Abstract
An electrical junction box for supporting a hanging load includes a base plate and a sidewall extending from it. The base plate has a pair of square bolts holes at opposite positions next to the sidewall. The sidewall has a pair of tabs bent inward, each tab having a bolt hole aligned with one of the square bolt holes. A square necked carriage bolt extends through each square bolt hole and its aligned tab bolt hole, with a lock nut on each of the bolts for supporting the hanging load. A spacer sleeve surrounds each of the bolts, between the base plate and the tabs, forming a rigid structure when the nuts are tightened. The sidewall further includes mounting holes for side mounting of the junction box for a supporting structure, permitting flush mounting of the box relative to a ceiling.
