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.
