But this versatile duct is often susceptible to kinks and sags that restrict air flow. The Malco™ FDS1 Flexible Duct Support eliminates air flow restrictions and increases efficiency to dramatically reduce utility bills and improve heated or air-conditioned room comfort. A properly supported 90 deg duct elbow typically improves air flow efficiency 10 to 40%. 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 Dia of flexible fiberglass wool duct as well as un-insulated flexible duct. Strong, but lightweight, 100% recycled polymer support will not weigh down ducting.
