Product review (1 stars): Did not fit my Emerson three-bolt mount
Tried hard to make it work. The adapter was too small for the three-bolt mount used by my old Emerson disposal. When I finally got it in place, my new Waste King 2600 simply fell through the retaining ring. I had to return both the 2600 and the kit . . . with shipping charged to me.

I needed the kit because I wanted to use my existing polished brass sink flange. Otherwise, I would have used the hardware supplied with the 2600, which looked as if it would work nicely.

And, yes, I tried everything. I spoke with Waste King, viewed their videos and read their literature, so I'm confident I did what I was supposed to do. Problem was that the outside diameter of the part of the kit that mates with the existing three-bolt mount system was 82mm, while the outside diameter of my old Emerson was 89mm. The kit piece simply isn't large enough

I went to Lowes, bought an Insinkerator, which is made by Emerson, and installed it with no problem.
