ABSTRACT:
A strainer device for preventing particulate matter from entering a drain system is provided. The device includes a strainer frame including a box portion and a flange portion. The box portion includes a primary outlet for liquids which is covered by a filtering device. Additionally, the box portion includes at least one secondary outlet along a side wall of the box portion, which is also covered by a filtering device. The present strainer device is designed such that when the primary outlet becomes clogged, liquid can flow through at least one of the secondary outlets. The flanged portion of the device is designed to overlap and extend beyond the sink or receptacle in which the strainer device is placed. The annular flange defines the inlet of the strainer device and includes a tapered portion and a grate recess in which a grate can be placed.
