Abstract: Closure of the opening for a fireplace or the like is effected by a plurality of plates or panels which are stored in stacked relation in a housing above the fireplace opening when not in use. The housing includes a biasing arrangement for maintaining pressure against the top of the panel stack so as to urge the panels towards a downwardly opening slot in the rear of the housing. A pair of channel members communicate with the housing slot and are affixed on either side of the opening. The bottom panel of the stack includes an externally accessible handle or the like for sliding this panel into the channels. A series of edge hooks cooperate to serially withdraw the panels from the housing and likewise cooperate to urge the panels serially back into the housing.
