Abstract
A plastic mounting plate closes a electrical box which delivers wires to an alarm unit or emergency light or the like. The alarm unit is mounted to the mounting plate by a snap connection and a tab-in-slot connection, without requiring the use of a tool. The mounting plate is connected to the electrical box by screws which engage threaded holes provided by the electrical box. The mounting plate can be mounted to either a single-wide electrical box or a double-wide (4×4) electrical box and provides corresponding holes for connection to either box. An alternate mounting plate for a single-wide electrical box is also provided.
