AC Infinity Wall-Mount Duct Grille Vent for 4-Inch Ducting

Versatile air flow solution for walls, cabinets, and tight spaces

The AC Infinity Duct Wall-Mount Grille is designed to sit flush on a wall or inside a cabinet to supply or exhaust air through a 4-inch duct. Constructed from flame-retardant polypropylene, it accepts paint to help it blend with your room or setup, turning a practical vent into a nearly invisible component of your ventilation plan.

With an internal manual damper, you can adjust airflow on the fly by simply popping off the face cover. The grille ships with all necessary screws and mounting hardware, making it straightforward to install on a wall or inside a cabinet. Note that duct clamps are not included, so consider your ducting setup when planning installation.
