• Supports 90 deg elbow for flexible duct Quickly installs on 4 - 16 in duct diameter Lightweight 100% recycled polymer construction Made in USA

Flexible fiberglass wool duct is a popular choice for residential and commercial heating and cooling. 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 - 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 - 16 in diameters of flexible fiberglass wool duct as well as un-insulated flexible duct. And the strong, but lightweight, 100% recycled polymer support will not weigh down ducting.
