Product review (1 stars): Poorly designed and clearly not like the previous disposal guards I have purchased
It fits the Sinkmaster drain correctly.  But the cutouts are too tight.  The drain hole is also too small.  Every little thing gets caught and I use a wooden spoon poker every time I turn on the faucet.  The water doesn't even drop into the hole well.  Poorly designed and clearly not like the previous disposal guards I have purchased.  Go back to the drawing board on this design Lasco.  If I wanted a catch screen for stuff I would buy one.
