Type: Spiral Duct Grille

This aluminum spiral duct grille is designed for HVAC contractors and facility teams finishing exposed duct runs. It covers an 18 in. x 8 in. duct opening while directing supply air or allowing return-air intake.

The pre-assembled grille has an all-aluminum, mill-finish construction with a rigid frame and foam gasket. Its 3/4 in. blade spacing and adjustable scoop support directional airflow or an open intake configuration. The grille is designed for spiral duct applications and has ±1/32 in. tolerances for duct fit.

Key Features:

  • All-aluminum construction: Provides lightweight strength and corrosion resistance.
  • Adjustable scoop: Allows airflow to be directed or opened for intake use.
  • Foam gasket: Helps reduce air leakage and rattling at the duct connection.
  • Pre-assembled design: Supports faster installation.
  • Low-profile silver finish: Provides a clean appearance on visible ductwork.

Choose this 18 in. x 8 in. grille for exposed spiral duct installations that need a pre-assembled aluminum grille for supply or return airflow.
