ABSTRACT:
This invention relates to an apparatus for securing a projector. The apparatus is mountable to a ceiling drop pipe and comprises a cage and a drop pipe connector assembly. The cage has a plurality of interconnected members that together define an enclosure for housing a projector and impeding removal of the projector from the cage. At least some of the members are connected together by a member fastener that is fastenable only from inside the cage. The position of at least some of the members can be adjusted relative to other members so that the size of the enclosure can be adjusted to fit the projector snugly therein, thereby impeding access to the fastener.
