Malco’s Underwriters Laboratories-classified and GreenSpec-listed FDS1 flexible duct support eliminates airflow restrictions and increases efficiency to dramatically reduce utility bills and improve room comfort, the maker says. A properly supported 90-degree duct elbow typically improves air flow efficiency 10 percent to 40 percent, officials say. A Malco duct support quickly installs on new or existing flexible duct. The versatile FDS1 design uses either 36- or 48-inch nylon cable ties to accommodate 4- to 16-inch diameters of flexible fiberglass wool duct, as well as uninsulated flexible duct.
