A Zip-A-Duct™ Fabric Inlet Section is required for each and every Fabric Duct run. Diameter is determined by the total system CFM or the total CFM used for the specific duct run. The inlet provides the transition from Metal to Fabric. It is clamped onto a metal starter collar and then provides the first zipper for the fabric conversion. Requires straps to attach to collars.
Custom colors in Black, Blue, White, Green, and Red are available upon request. Please contact your sales representative.
