Flange – 23mm profile/strong
Strong, virtually leak-free rectangular duct connection flange. Our flange comes with an integral mastic sealant to seal against the duct wall and eliminate air loss. Our flange is manufactured from roll-formed galvanized steel and features a unique down turned corner to provide a greater seal than many other brands on the market.
