Beschreibung
Zusammenfassung:	A flow control device that includes an orifice placed in an opening of a duct. A flexible sheet of material is wrapped around a first duct section to include an extended section which is crimped inwardly around the face of the orifice. A sleeve with tightening straps can be wrapped around the aligned first and second duct sections, with the sections having the orifice positioned between. A bead on the duct sections can assist in orifice positioning, attachment, and sealing. The orifice can also be attached to the duct section using tabs and a retention ring. A duct sleeve is also provided for placement in the opening of a duct. The duct sleeve includes a reception slot that receives an orifice plate that is attached in a secure and sealable manner.
