Flexible fiberglass wool duct is a popular choice for residential and commercial heating and cooling, but it can be prone to kinks and sags that restrict air flow.
The Malco FDS1 Flexible Duct Support eliminates airflow restrictions and increases efficiency, to dramatically reduce utility bills and improve heated or air-conditioned room comfort. A properly supported 90-degree duct elbow typically improves airflow efficiency 10% to 40%, Malco sources say.
A Malco Duct Support quickly installs on new or existing flexible duct. The versatile FDS1 design uses either 36- or 48-in. nylon cable/zip ties to accommodate 4-in. to 16-in. diameters of flexible fiberglass wool duct, as well as un-insulated flexible duct.
