Flexible air duct connects the main supply air duct to a ceiling-mounted diffuser or register through an insulated square-to-round adaptor and collar. Stainless steel drawbands and nylon tie-wraps secure the flexible duct, which is limited to a maximum length of five feet without splices. A forty-five degree rigid round saddle tap branches from the main supply duct, incorporating a volume damper equipped with edge seals and a standoff locking quadrant. The sheet metal can transitions into the diffuser assembly set within the ceiling, requiring accessible volume dampers.
