This is a vent duct adapter for a Honeywell AC so you can add a 6" flexible duct to the intake side, this should also work on the discharge side as well. You would attach the flexible vent duct to this piece and tighten it using a hose clamp. My model is a MM14CHCS however this probably will work on other similar models.
