Flat Base Premier Damper Cap
Our Flat Base Damper Cap is designed to be motared into the crown or fit directly onto an existing top plate. The base plate is made from 18ga 304 stainless steel, and extends 2" past the screen for ease of installation.
Just like the original Premier Damper Cap, the Flat Base Damper Cap has an insulated lid, and will withstand temperature extremes from -85° to +450°F. The expanded mesh screen is 3/4" with an option of 5/8" California mesh.
