Imperial 10 in. D 26 Ga. Galvanized Steel Duct Start Collar

This Imperial 10-in Airtight Adhesive Take-Off provides a reliable transition from a rectangular duct or a plenum to a round pipe or insulated flexible duct. A peel-and-stick self-adhesive gasket helps to create an airtight seal, and sheet metal screws reinforce the secure fit (screws sold separately). Built to last, the adhesive take-off is made from 26-gauge galvanized steel for rust resistance and durability. It is suitable for use in most heating, venting, and air conditioning applications.
