Enclosure Louvers
Relieve heat buildup and prevent condensation from forming inside enclosures and other small spaces.
All aluminum louvers have small openings between their blades to stop bugs from getting inside your enclosure. Anodized aluminum louvers withstand corrosion better than unfinished and powder-coated aluminum louvers. They’re good for settings such as saltwater environments. Darkroom louvers have a shield on the back that blocks out light—use them where light control is a concern.
