Product review (5 stars): Good adapter to connect Waste King Disposers to Insinkerator Strainer
The Waste King disposer is a great unit that comes with a generic flange and strainer requiring the removal of the existing and installation of the new using plumber's putty.

If you're replacing an Insinkerator unit, you can replace the flange on the Waste King unit with this adapter and then use the three-point locking rink to connect the new unit to the Insinkerator strainer. This saves a lot of work and some mess.

I donated the unneeded parts to our local Habitat for Humanity Restore to avoid throwing them away - I'm sure they'll find a new home!
