Direct-fit mounting adapter

The InSinkErator 11327-A Mounting Adapter provides a direct-fit connection between a compatible disposer and a standard sink opening. It is intended for professional installers and maintenance teams who need a reliable, stainless-steel interface for Insinkerator models using the 11327A reference.

Collar and flange adaptors included

The package supplies collar adaptors and a sink flange adaptor so the installer can complete the joint without sourcing separate hardware. These bundled components match the adapter’s 5 1/8 in overall diameter and 4 1/2 in sink opening diameter, reducing assembly steps on site.

11327A model compatibility

Fitment is determined solely by the manufacturer model number 11327A and the Insinkerator brand. If the disposer carries a different model reference, this adapter will not align with the mounting assembly.

Questions about this item

Will the stainless-steel collar or flange adaptors ever need replacement under normal use?

The stainless-steel collar and flange adaptors resist corrosion and are built for the life of the disposal; no scheduled replacement is required.

What limits continuous operation first — motor heat or the mounting seal?

The mounting seal is the limiting factor; if the collar loosens over time, vibration can break the watertight joint before the motor overheats.

Does the adapter add noticeable vibration or noise when the disposer runs all day?

The precision stainless-steel fit dampens vibration, so the adapter itself adds no measurable noise or heat during extended operation.
