Southwark Metal 98WD_10IN Spin-in Collar Scoop Damper 10 in

Product Description

The SOUTHWARK METAL 98WD_10IN is a sheet metal ductboard spin-in collar with an integrated scoop and damper, designed for HVAC air distribution systems. Constructed from hot dip galvanized steel, this collar provides a secure, airtight connection point where a branch supply run connects to a ductboard trunk. The 10-inch diameter fits standard ductboard applications and includes a built-in scoop to direct airflow into the branch and a damper for field-adjustable flow control. HVAC installers and sheet metal mechanics are the primary trades that work with this fitting.

This spin-in collar is used in residential and light commercial forced-air systems where ductboard serves as the trunk line material. The spin-in design allows the collar to seat and lock into a field-cut hole in the ductboard surface, simplifying branch takeoff installation. The scoop deflects conditioned air from the trunk into the branch run, improving delivery efficiency. The damper allows the technician to balance airflow at the takeoff point without adding a separate volume control damper downstream.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in HVAC environments
• Integrated scoop directs airflow from trunk ductboard into the branch run
• Built-in damper allows field balancing of branch airflow at the takeoff
• 10-inch diameter spin-in design seats securely into ductboard without additional hardware
• Meets ACCA and SMACNA applicable standards for sheet metal duct fittings

Compatibility

Designed for use with sheet metal ductboard trunk systems requiring a 10-inch diameter spin-in collar takeoff fitting.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal mechanics following SMACNA duct construction standards. Power down the air handling unit before cutting into the ductboard and seating the collar. Use a ductboard cutting tool sized to the collar diameter to produce a clean, tight-fitting hole. Seal the collar perimeter to the ductboard surface with approved duct mastic or foil tape per local mechanical code requirements.
