Southwark Metal 98WD_8IN Spin-in Collar Scoop Damper 8 in

Product Description

The SOUTHWARK METAL 98WD_8IN is a sheet metal ductboard spin-in collar with an integrated scoop and damper, designed for use in forced-air HVAC distribution systems. Constructed from hot dip galvanized steel, this 8-inch diameter collar provides a durable, corrosion-resistant connection point where branch takeoffs meet ductboard trunk lines. The built-in scoop directs airflow into the branch run, while the damper allows field adjustment of airflow volume at the takeoff point. Licensed HVAC technicians and sheet metal installers use this fitting during new construction and retrofit ducting projects.

This spin-in collar is suited for residential and light commercial HVAC duct systems where ductboard is the primary trunk or branch material. It installs directly into a field-cut or pre-cut hole in the ductboard surface, spinning and locking into place without additional fasteners in most applications. The scoop-and-damper configuration makes it appropriate for supply air branch takeoffs where balancing airflow between zones or runs is required on the job.

Key Features

• Hot dip galvanized steel construction resists corrosion in attic and crawlspace environments
• Integrated scoop directs conditioned air efficiently into branch duct runs
• Built-in damper allows field airflow balancing without additional hardware
• 8-inch diameter fits standard ductboard takeoff applications
• Spin-in design enables fast, secure installation into ductboard panels
• Meets ACCA and SMACNA applicable standards for sheet metal duct fittings

Compatibility

Designed for use on sheet metal ductboard systems. Suitable as a supply air branch takeoff fitting in ductboard trunk-and-branch HVAC distribution layouts.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal installer in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air handling unit and confirm the system is de-energized before cutting into the ductboard or installing the collar. Use a hole saw or ductboard knife sized to the 8-inch collar diameter for a clean, snug fit. Secure all connections and seal duct penetrations with approved mastic or foil tape per applicable code requirements.
