Supco DS3 Duct Saddle

Stop the sag

Supco DS3 Duct Saddle Strapping System makes it faster and easier than ever to retrofit old saggy duct systems. The average duct system is only about 57% efficient. Restrictions critically reduce airflow and prevent proper efficiency of the HVAC system. Low airflow is the #1 cause of compressor and blower motor failure.

Key Features & Benefits

  • Fast and easy installation with NO TOOLS REQUIRED
  • Installs on existing strapping to straighten ducts, stop the "strap strangle" and improve airflow
  • 12" saddle length eliminates kinks and sags
  • Allows strapping at 6' intervals and yields a 5' span between supports for code compliance
  • Works with all types of strapping (1/2" to 1-1/2" metal, and polyweb strapping)
  • Concave shape allows 930% more surface contact area with round, flexible HVAC ducting compared to strapping alone
  • Great upgrade for a service contractor. Improvement of airflow can be demonstrated to homeowner post installation


Saddle Length 12 inches
Strapping Interval 6 feet
