Product review (5 stars): Yes it Fits Titan Disposal Units!
For some reason nobody listed Titan disposal units that Costco was selling.  This fits my Titan 1.25 hp disposal unit perfectly and at nearly half the price of Lowes who didn't carry it/special order for 11 dollars.  As disposal units go the Titan outlasted my Insinkerator and waaay more powerful, its 4 yrs old.  Now I am thinking I should buy another one just in case.
