ABSTRACT:
A drain covering composed of an upper straining region and a lower threaded region. The straining region is in the shape of any conventional drain and has a plurality of straining holes set in various locations on the drain piece. The threaded region is connected to the bottom of the drain, and can be connected to any standard sink. A number of holes are also provided in the strainer to allow a rod to tighten the drain covering into the sink. Waterproof putty is used to seal the connection between the drain covering and the sink.
