This 4-inch galvanized steel ducting collar is designed to connect flexible or rigid ducting to flat surfaces in ventilation, heating, and cooling systems. Its ridged and crimped pipe end provides a secure grip on ducting, while the wide flat flange creates an airtight seal when mounted to walls, ceilings, floors, or cabinets. The galvanized steel body, finished with a corrosion-resistant zinc coating, withstands high temperatures and harsh environments. Ideal for retrofitting ventilation to exhaust air efficiently and prevent particle intrusion.
