Southwark Metal 58106 Sheet Metal Duct Reducer 10x6

Product Description

The SOUTHWARK METAL 58106 is a sheet metal duct reducer designed to transition airflow from a larger duct opening to a smaller one within a forced-air HVAC distribution system. Sized at 10 inches by 6 inches, this fitting connects a 10-inch upstream duct section to a 6-inch downstream run, maintaining system static pressure balance through the transition. HVAC technicians and sheet metal contractors install this type of reducer during trunk-and-branch duct fabrication and modification work. It is constructed from sheet metal, consistent with standard SMACNA duct fabrication practice.

This reducer fits into residential and light commercial forced-air systems where duct layout requires a step-down transition between trunk lines and branch takeoffs. Common install scenarios include air handler distribution systems, furnace duct retrofits, and branch extension work where a 10-inch main must feed into a 6-inch branch run. The fitting is appropriate for supply or return applications depending on system design.

Key Features

• 10-inch to 6-inch transition for step-down duct sizing
• Sheet metal construction compatible with standard SMACNA duct practices
• Suitable for supply or return duct applications
• Integrates into trunk-and-branch forced-air distribution layouts

Compatibility

Designed as an OEM-style sheet metal fitting for use in residential and light commercial forced-air duct systems requiring a 10-inch to 6-inch round or rectangular duct transition.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal contractors. Power down the air handling unit or furnace before making any duct modifications. Secure the reducer with sheet metal screws and seal all joints with UL 181-rated duct mastic or foil tape in accordance with local mechanical code requirements. Do not install in applications exceeding the fitting's rated pressure class.
