The Delta Duct FD3 – RN variant introduces a reinforced outer jacket for environments requiring extra mechanical protection. The outer jacket is made of reinforced metalized PET laminated over clear polyester, while the inner core remains a double layer of clear polyester. This reinforced construction makes it highly resistant to tears and punctures during installation and maintenance.

  • High-Traffic Service Areas: Used in service floors and utility rooms where the duct is more likely to be handled or bumped by maintenance personnel.
