Type: Spiral Duct Grille

This aluminum spiral duct grille is designed for HVAC professionals and facility teams finishing exposed duct runs. It provides directional supply airflow or an open intake for return-air applications while giving visible ductwork a clean, low-profile appearance.

The grille is made of aluminum with a mill finish and is supplied pre-assembled. Its rigid frame is designed for spiral duct fit with ±1/32 in. tolerances, while a foam gasket helps create a sealed fit. The adjustable scoop supports directional airflow or open intake operation, and 3/4 in. blade spacing is designed for smooth airflow. Product dimensions are 20 in. wide, 6 in. deep, and 2 in. high.

Key Features:

  • Aluminum construction: Provides lightweight strength and corrosion resistance.
  • Adjustable scoop: Allows directional airflow adjustment or open intake use.
  • Foam gasket: Helps reduce air leakage and rattling at the duct connection.
  • Pre-assembled design: Supports quicker installation.
  • Low-profile grille: Creates a clean look for visible ductwork.

Choose this 16 in. x 4 in. silver grille for spiral duct installations that need supply or return airflow control, a secure fit, and a streamlined finish.
