Abstract: A commercial refrigerated display case includes mullions for slideably receiving removable ballast drawers from the sides of the mullions for quickly and easily servicing fluorescent ballasts.

Abstract: A multi-pane insulated glass door assembly in which the forward pane of the glass unit extends outwardly a greater distance than the panes rearwardly thereof and is supported by an outer metal frame having a relatively narrow forwardly extending perimeter portion adjacent the peripheral edge of the forward glass pane so as to provide the door with a modernistic, substantially all glass front appearance. In one embodiment, the outer metal frame has a rear portion extending inwardly behind the forward glass pane and a molding is interposed between the forwardly extending perimeter portion of the metal frame and the peripheral edge of the forward glass pane to provide a finished appearance. A dark ink is affixed to an inside peripheral face of the forward glass pane for masking the peripheral components of the door assembly from sight through the forward glass pane from the front side thereof.

Abstract: A vent plate is attached to the bottom frame member of a door mounting frame of the insulated door assembly of a refrigerator unit. The vent plate includes passages which enable ambient air to be drawn into the cabinet of the refrigerator unit at a controlled location in order to avoid frost build up.

Abstract: A refrigerator cabinet light fixture assembly comprising an elongated base with an electrical socket at each end thereof, an elongated bulb supported between the sockets, and a clear plastic tubular sleeve concentrically supported about the bulb for defining an air insulating space therebetween. A plurality of stabilizing members are mounted on the base member intermediate the ends of the tubular sleeve for engaging the tubular sleeve and preventing relative movement between the sleeve and bulb for enabling the sleeve to protect the bulb from damaging impact of forces striking the exterior of the sleeve. The stabilizing members each have a base fixed to the light fixture base member and an outwardly extending sleeve engaging arm mounted for pivotal movement between an operative tubular sleeve engaging and retaining position and a retracted position out of engagement with the tubular sleeve for permitting removal of the sleeve and bulb from the fixture.
