Abstract: The present invention relates to a new and improved retaining device designed to hold articles in a top or bottom dishwasher rack preventing them from dislodging during a wash cycle. The device comprises a substantially rectangular net member attached to a window shade type roller assembly. The roller assembly may be removably attached to any side of a top or bottom dishwasher rack. The net member has a substantially centrally located aperture for receiving a dishwasher water tower allowing the device to be easily used to retain items placed in a lower dishwasher rack. The net member also has one or more mesh storage pockets on a side thereof allowing additional lightweight articles to be stored therein. Longitudinal stainless steel reinforcement strips are provided on the net member allowing it to be easily retracted within the roller assembly and allowing it to more tightly engage articles stored in the dishwasher rack.
