Southwark Metal 20_8X8 Trunk Duct Collar 8x8 Inch

Product Description

The SOUTHWARK METAL 20_8X8 is a straight starting collar designed for sheet metal trunk duct systems in forced-air HVAC installations. Fabricated from hot dip galvanized steel, this collar connects directly to a rectangular trunk duct to initiate a branch or transition point within the duct run. The straight body pattern allows for a clean, in-line takeoff configuration. HVAC sheet metal workers and mechanical contractors install this fitting during new construction and system retrofit work where a durable, corrosion-resistant starting collar is required at an 8 inch by 8 inch duct opening.

This collar is suited for residential and light commercial forced-air duct systems where a trunk duct requires a starting connection point. The 8 inch by 8 inch size fits standard rectangular trunk openings of that dimension. It is fabricated to meet ACCA and SMACNA standards, making it appropriate for systems designed and installed under those industry guidelines. Sheet metal mechanics typically incorporate this fitting during duct fabrication or when extending an existing trunk line.

Key Features

Compatibility

Designed as an OEM-style sheet metal fitting for use in rectangular trunk duct systems requiring an 8 inch by 8 inch straight starting collar connection, fabricated in accordance with ACCA and SMACNA standards.

Installation Notes

Installation is performed by licensed sheet metal workers or HVAC mechanical contractors. The duct system should be fully de-energized and the air handler or furnace powered down before any duct modification or fitting installation. Sheet metal screws and approved duct sealant or mastic should be used to secure and seal the collar per SMACNA installation guidelines. Follow local mechanical codes for duct support spacing and sealing requirements.
