ABSTRACT:
A panel for securing in a conventional sliding door opening to cooperate with the sliding doors therein has a swinging door flap at the bottom of a panel defined by vertical stiles which may be trimmed to suit varying door frame heights. The stiles bear fixed projections to fit horizontal apertures at the door stile and sliding projections to fit apertures in sill and top rail of the frame. The panel has an adjustable rail which overlaps the weather pane of the panel at top or bottom of the pane. The access door flaps swings from an intermediate rail which may be a part of a panel or a part of a sub-assembly mountable in any opening. The flap has imbedded magnets to arrest it closed and thin wiper edges to seal against weather, and is self-hinging in the intermediate rail.
