Southwark Metal 122SC-10 Ductboard Snaplock Collar 10 in

Product Description

The SOUTHWARK METAL 122SC-10 is a ductboard snaplock collar designed for connecting round duct to ductboard plenum and duct systems. This fitting features a snaplock seam that allows for quick field assembly without additional tools, making it a practical choice for HVAC installers working with fiberglass ductboard systems. The collar measures 10 inches in diameter and is designed to seat into ductboard material with a board thickness range of 1.5 inches to 2 inches. It provides a secure, airtight connection point where round branch duct transitions into a ductboard trunk or plenum.

This collar is intended for use in residential and light commercial HVAC ductwork installations. It is typically installed by sheet metal workers and HVAC technicians when fabricating or replacing ductboard trunk systems. The snaplock design speeds up installation on the job site, reducing the time needed to complete branch takeoff connections in attic, crawlspace, or mechanical room applications.

Key Features

• 10-inch diameter fits standard round duct of the same size
• Snaplock seam allows fast, tool-free field assembly
• Compatible with ductboard thickness ranging from 1.5 inches to 2 inches
• Designed for clean insertion into ductboard for a secure fit

Compatibility

Designed as an OEM-style replacement and new-installation fitting for fiberglass ductboard trunk and plenum systems using 10-inch round branch connections with board thicknesses of 1.5 inches to 2 inches.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal workers. Power down the air handling unit and confirm the system is depressurized before modifying any duct connections. The collar should be inserted into a field-cut hole in the ductboard and secured per local mechanical code requirements, with joints sealed using approved duct mastic or UL 181B-rated tape. Do not over-compress the ductboard material around the collar flange, as this can damage the board facing and reduce insulation integrity.
