Southwark Metal 142_10IN Storm Collar 10 Inch Round

Product Description

The SOUTHWARK METAL 142_10IN is a round sheet metal duct storm collar designed for use with 10-inch diameter duct penetrations. Constructed from hot dip galvanized steel, this collar provides a weather-tight seal where round ductwork or flue pipe exits a roof or wall assembly. It is designed to prevent water intrusion at the penetration point and is a standard component in residential and light commercial HVAC duct and venting installations. HVAC technicians and sheet metal contractors install this collar as part of a compliant duct or vent system termination.

This storm collar is suited for residential and light commercial applications where a 10-inch round duct or pipe passes through a roof or exterior wall surface. It is commonly used alongside roof flashings and vent pipe assemblies in forced-air heating and cooling systems. Compliance with ACCA and SMACNA standards makes it appropriate for use in systems where these guidelines govern ductwork fabrication and installation practices.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in exterior applications
• 10-inch diameter round profile fits standard duct and pipe penetrations
• Meets ACCA and SMACNA applicable standards for duct system components
• Round collar design seats evenly around pipe or duct for consistent weather protection

Compatibility

Designed as an OEM-style replacement and standard-fit component for 10-inch round duct and pipe penetration assemblies in residential and light commercial HVAC systems built to ACCA and SMACNA standards.

Installation Notes

Installation is typically performed by a licensed sheet metal contractor or HVAC technician. The duct system should be de-energized and any associated equipment shut down before service begins. Follow SMACNA ductwork installation guidelines and local building codes for proper collar placement, sealing, and fastening at roof or wall penetrations. Do not compress or distort the collar during installation, as this may compromise the weather seal.
