An open basket of a resilient mesh material having first and second side edges of a frictional flexible material. The side edges are adapted to provide for positioning of the basket either immediately partially between a vent cover and the duct, or alternatively, fully within the duct at a location immediately below and spaced apart from, the vent cover. The mesh size of the basket is chosen to preclude the passage therethrough of commonly experienced objects, such as rounded objects such as marbles, elongated objects such as nail clippers, pens, coins, etc. any of which may pass through the slots defined in the vent cover.
