InSinkErator Model 66 – Top-of-Range Food Waste Disposer, M Series

The InSinkErator 1972166 Model 66 is the flagship of the M Series, the compact line engineered for under-sink installations where space is at a premium. Manufactured in the USA, this food waste disposer features the high-torque Dura-Drive single-phase induction motor at 0.75 HP (560 W): it runs 20% quieter than standard models thanks to integrated sound-reduction technology.

Permanently lubricated upper and lower bearings require no maintenance. The manual overload reset protects the motor from accidental jams.
