Today, the Flexmaster U.S.A.® Return Air Kits are the perfect solution for all your attenuation needs in return air and transfer air ducts.
Substantially less expensive than internally lined sheet metal ductwork, the Flexmaster U.S.A.® Return Air Kits provide a superior acoustical solution in an easy to install flexible duct kit.
The Flexmaster U.S.A.® Flexible Return Air Kits are manufactured to meet the highest quality standards in strength, permeability and fire resistance required in a flexible air duct.
