ABSTRACT:
A security cover for a conventional telephone installation backboard, characterized by use of a pair of mounting members rapidly attachable to the backboard, one of which includes a hinged door panel which may be pivoted toward and away from the other mounting member to provide selective access to the backboard. The pair of mounting members are so constructed to permit mounting the backboard without disturbing any existing wiring connections on the backboard and once installed, the hinged door panel may be locked in a close position to prohibit unauthorized access to wiring disposed on the backboard.
