This silver aluminum spiral duct grille is for HVAC professionals and facility teams finishing exposed duct systems. It provides directional supply airflow or an open intake option for return-air applications.

The grille is made of all-aluminum with a mill finish and comes preassembled. Its rigid frame is designed for spiral duct installation, with ±1/32 in. tolerances for duct fit, a foam gasket for a sealed fit, 3/4 in. blade spacing, and an adjustable scoop for airflow direction or open intake operation.

Key Features:

  • All-Aluminum Construction: Provides lightweight strength and corrosion resistance.
  • Adjustable Scoop: Lets users direct airflow or set the grille for open intake.
  • Foam Gasket: Helps minimize air leakage and rattling at the duct connection.
  • Preassembled Design: Reduces installation preparation time.
  • Low-Profile Appearance: Gives visible ductwork a clean, contemporary look.

Choose this 20 in. x 4 in. grille for spiral duct supply or return installations where a sealed fit, adjustable airflow, and a silver low-profile finish are needed.
