This aluminum spiral duct grille is designed for facility and HVAC professionals who need to distribute or return air through exposed spiral ductwork. Its adjustable scoop supports directional airflow for supply use or an open intake position for return applications.

Key Features:

  • Aluminum construction: Provides lightweight strength and corrosion resistance for duct installations.
  • Adjustable scoop: Lets users direct supply air or open the grille for return-air intake.
  • Foam gasket: Helps reduce air leakage and rattling at the duct connection.
  • 3/4-inch blade spacing: Supports smooth, directional airflow.
