Always open, these are our most basic wall louvers.

Mount these louvers into openings that are too small for most louvers. They are sized for use in block and brick walls.

The included filter cleans the air as it passes through these louvers.

Thicker than standard movable-blade wall louvers, these are rugged and dependable.

Use these louvers in harsh environments—they won't rust.

With a gasketed sealing kit, these louvers shield your enclosure from dirt, moisture, and weather while regulating heat and stopping condensation from forming inside.

A spring-loaded fusible link locks the blades closed if the temperature reaches 167° F. Louvers meet UL 10C fire requirements.
