What’s in this rate
This unit is setting one rectangular duct silencer in a prepared duct run. The HVAC technician positions the rectangular attenuator casing, connects both duct flanges as furnished, seals the joints, and leaves the silencer ready for hang and balance. The rate is per each rectangular duct silencer. This rectangular in-line attenuator stays distinct from supply diffuser faces, duct hangers, and flexible connectors. Round silencers, acoustic liner, and external wrap are separate units.
