Abstract
A fluorescent lamp fixture has a pair of lamp socket assemblies which are normally retracted for shipment but which are pivoted outwardly for installation. The fixture comprises a channel member having a web with a pair of upstanding sidewalls and a pair of socket assemblies pivotally-mounted between the sidewalls. The sidewalls have aligned shaped apertures each with an entrance slot, and the base member has a pair of ear assemblies shaped to slide downwardly through the slots and into the apertures during assembly and to lock the socket assembly to the channel member when the socket assembly is pivoted through a predetermined angle. Cooperating latch assemblies are provided on the channel member and socket assembly for locking the socket assembly in its extended position. Closure plates are provided for the ends and top of the channel.
