The "Thermo-Saddle" is designed to work with this company's "Button-Lok" hanger strap to make an exceptional installation system that allows round flex duct to be hung prior to installing a suspended ceiling. The Thermo-Saddle eliminates pinching and compression of the duct insulation, leading to greater R-valve and increased airflow.
