Middle Atlantic APV-4 Rack Mounted Vent Panel, Hinged, 4U RMS

Streamline rack maintenance and improve cooling for security and surveillance systems with the Middle Atlantic by Legrand APV-4 4U hinged vent panel. Designed as a practical rack accessory, the APV-4 provides fast, tool-free access to rear connectors and cabling thanks to its captive 10-32 threaded thumbscrews and one-side hinge. The vented panel option enhances airflow to reduce heat buildup around sensitive monitoring and networking equipment, while the vent pattern limits accidental contact.

Built from 13-gauge black powder-coated steel and sized for standard 19" racks (4U / 7" height), this access panel balances durability with a clean professional look for control rooms, server closets and security enclosures. Its machinable steel construction also supports custom cutouts when specialized connector access is required. Whether you manage AV installs, surveillance cameras, or critical network gear, the APV-4 minimizes downtime and simplifies routine servicing.

Add the APV-4 to your rack accessories to speed installations and protect equipment — ideal for security, monitoring and IT deployments that demand reliable access and ventilation.
