Type: Spiral Duct Grille

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.
