ABSTRACT:
A ceiling fan support for supporting a fan in a hole through a ceiling. The support is comprised of telescoping sections and is insertible through a hole in the ceiling and has teethed braces at each end adapted to be situated against a pair of spaced joists in the ceiling on each side of the hole. A tool is inserted into aligned holes in the telescoping sections and one of the telescoping sections is moved longitudinally until teeth on the braces dig into the joists thereby firmly supporting the support in the hole in the ceiling while a constant downward pressure is exerted on the telescoping sections maintaining them in fixed telescoped position.
