Reducers from The Duct Shop are the perfect fitting to use when you need to change from one size duct to another size. All Reducers are manufactured from the highest quality galvanized steel. They are perfect fittings for maintaining maximum airflow through your system while changing to the needed duct size.
Installation Tip — To install Reducers, you simply slide the reducer into the item you are attaching to and fasten with sheet metal screws or duct tape. We recommend that you seal the seams with a duct sealant after installation to prevent any air leakage, increase the efficiency of your system and reduce your utility bills. See installation tip for Flexible Duct or Sheet Metal Duct, depending on which type you will be attaching to any specific HVAC system.
