Premium PCA Hose

The flat duct, which is compact and insulated, is a very adaptable heating and cooling duct. Because there are no wires used in its construction, it may be rolled up and flattened for small storage when not in use. The Flat Duct hose is made of vinyl-coated heavy-duty, flexible, two-ply fabric that is highly abrasion resistant. Non-rip nylon is used for the inside structure, and the insulation between the plies is moisture-proof.
