Asked by: Luc1
No, that model uses a different mounting type, it uses a bolt and special type of washer to accommodate different thicknesses of counter tops including granite.

Extension for Involve Hot Water Dispensers is rated 4.0 out of 5 by 7.
Rated 5 out of 5 by from Hot water dispenser extendender works! I am so glad Insinkerator solved the issue with our over 10 year old hot water dispenser. The extender through our new stone counter is the perfect solution. Thank you!!!

Rated 1 out of 5 by from Extension for In-sinkerator hot water dispensers This product is not worth anything. It is wrongly designed. We tried to use it and gave up. Fortunately we had an adapter made for the application using a Kohler hot water dispenser and it had the same threads as the In-sinkerator hot water dispenser. The reason for using this product is to install the hot water dispenser on a thicker piece of granite. This is a fairly common problem. However, when the sink is installed underneath the granite the holes in the sink aren't necessarily concentric with the sink holes and, if they are not exactly concentric then the washers for the extension will not fit through the sink hole to go against the granite hole for a solid mounting. And, as such, one can never tighten the hot water dispenser. Our solution was to use a special piece machined to fit through the holes and tighten the dispenser.

Rated 5 out of 5 by from Hot Water Despenser Have had this product now for 5 years and my wife and I love it. Great for hot cereals, drinks & recipes. When we changed out our counter top and it was thicker than our old one I was very glad that there was a extension that attached .

Rated 5 out of 5 by from Evolve Extension This little extension allows one to use the hot water dispenser with thicker (e.g., granite) countertops. Without it, the spigot can't be used (threads don't extend below the countertop). Works well. My only complaint is that this little plastic piece costs $30...

Rated 5 out of 5 by from Worked Great Ordered it wondering if it would work ok after reading other reviews, Got it and it worked perfect for me, installed my insinkerator instant hot on a granite counter top and it tightened right down firmly without stripping or breaking as others mentioned so I was a happy camper!

Rated 2 out of 5 by from extra This extension is something that should be provided by in-sink-erator when you purchase an instant hot water dispenser. Once I received the extension it provided more problems in that the nut provided with the instant hot water dispenser to tighten the unit to the counter would strip on the threads of the extension. Overall the whole installation process was made even more difficult.

Rated 5 out of 5 by from Product was as advertised, worked well, and was received promptly. The part fit properly on my dispenser and in the counter-top mounting hole. It was easy to install.
