Quick-Open Duct Access Panels

The panels open and close by turning the knobs. Also known as cleanouts, panels cover cutouts in duct to provide access for inspection and cleaning. They’re made of galvanized steel for good corrosion resistance. All have a gasket to create a tight seal. Use the included template to make the cutout.
Style D panels have an observation view port that lets you quickly see if dust or debris is blocking the airflow in your duct without having to open the panel.
