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

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.

These conductive aluminum screens block electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent electrical problems such as radio static and faulty signals. Made of mesh, they let air flow through, so the pressure in your enclosure stays constant as temperatures fluctuate.
