ABSTRACT:
An extensible hanger support providing a spanning connection between two spaced-apart joists or the like for supporting therefrom such items as ceilings fans, lights fixtures and the like. The support includes first and second extensible members which are telescopically axially movable between a fully collapsed condition and a fully extended condition. These extensible members employ cooperative means which are normally in threaded engagement in such a manner that high speed rotation of one of the members relative to the other results in axial movement toward either the fully collapsed condition or the fully extended condition depending upon the direction of rotation. Each of these extensible members has a free end which carries joist engaging means for respectively engaging a ceiling joist.
