Abstract: Internally illuminated emergency signs are typically placed in elevated locations which are awkward for electricians to reach, yet must be securely mounted. It is therefore difficult and time-consuming to make wiring connections after the mounting operation is completed. In order to facilitate both quick and easy wiring of the sign, and secure mounting thereof, an improved canopy features a projecting bracket which slips into a slot in a side or top of the sign housing, and engages over horizontally extending screws. Rapid, yet secure mounting of the sign is achieved by cantilevering the sign on the bracket, if side mounting is used, or by use of a locking pin, if top mounting is used. The locking pin keeps the screws from sliding laterally with respect to the bracket.
