Jalousie windows - vertical plastic rectangle with 3 convex 'columns' - one per window frame, at lower left
It's not clear what this piece's function is. On one window frame, it came loose and was lost lost. The others are snapped into place.
Its height is 5 5/8" and width is 3/4". Depth is < 1/4".
I'll appreciate your identifying this part and advising if I can order it.
Thanks, Fred S.
