Abstract
A two part grille with interlocking connections molded from opaque plastic allows one or more screens or filters supported inside the grille and provides a configuration which allows its parts to be fitted on opposite sides of an opening in a wall or a door locked together by a mortise and tenon joint so that no screws are necessary, and the two part grille further has intermediate spacers used to accommodate differing thickness of a wall or the like.
