18"x18" Anodized Aluminum Exterior Wall Louver, Weatherproof Rain & Rust Resistant Vent Cover

Product Overview

The 18"W x 18"H white aluminum exterior gable vent carries air through the opening through an exterior wall opening. Extruded aluminum resists rust and weathering outdoors, a durable, weather-resistant choice. Select this exterior gable vent by its wall opening size, not the overall face size, so it seats correctly on the first fit.

Key Features

• Aluminum construction: Aluminum keeps the exterior gable vent rigid during installation and resists warping over time.
• White finish: The white finish coordinates with common flooring, trim, and hardware.
• Right-fit sizing: Ordered by wall opening size, this exterior gable vent matches standard duct dimensions and cuts wrong-size returns.

Dimensions and Specifications

Is This the Right Vent for Your Opening?

Choose this exterior gable / wall louver for passive ventilation of an attic, gable, or crawl space. It mounts on an exterior wall or gable end and lets air move in and out through a louvered, screened face. This is a passive exterior vent, not an HVAC supply or return grille.

How to Measure for This Vent

Remove the existing vent and measure the width and height of the wall opening, not the outer face of the old cover. Match those two numbers to the nominal size above. The overall face measures 20"W X 20"H.

Installation

Position the exterior gable vent over the wall opening with the finished face facing the room. Confirm the frame sits flush against the exterior wall surface before marking the screw points. Secure it with the included screws without overtightening, since excess force can distort the frame.

What's Included

• 1 x exterior gable vent
• Mounting screws

Ductwork, wall anchors, and installation tools are not included.

Care and Maintenance

Clean the exterior gable vent with a soft, damp cloth and mild soap. Avoid abrasive chemicals that can damage the white finish. Dry the surface to keep moisture off the metal.
