A:Answer Hi Cwils, thanks for reaching out! There are no limitations as to what type of sinks our units can be installed onto. As standard, most sinks come with a 3.5 inches (90mm) sink hole and our disposals are designed to fit these, you just need to check that you have enough space under your sink to fit the unit. If you’ll need a power adapter, we have a Power Cord Kit model CRD:00 that contains all the necessary parts to install a cord on an un-corded disposer.
