Abstract
A ceiling fan and electrical outlet box support for supporting a ceiling fan between a pair of ceiling joists, includes a transversely oriented rigid threaded rod with a joist engaging piece threadedly received on one of the rod for telescopic movement as the rod is rotated, and a second joist engaging piece rotatably mounted on the other end of the rod whereby upon rotation of the rod the joist engaging pieces may be caused to engage the adjacent inside surfaces of a ceiling joist. The rod is rotated by applying a wrench to a pair of nuts which are jammed together over a prepared ceiling opening at some location between the joists. Hanger brackets in the form of eye bolts are slid onto the rod, on either side of the nuts, and support a generally U-shaped ceiling fan support bracket from the rod and also support an electrical junction box. A block of elastomeric material is positioned between the outlet box and the rigid rod, at the driving nuts, to take up vibration and slack.
