Keep servers, network switches, surveillance recorders and AV components running reliably with the Middle Atlantic by Legrand FILTER-R-4-2K filter kit. Designed for CWR and VWM rack series, this rack accessory delivers dust filtration and improved airflow to protect sensitive electronics in security, monitoring and networking environments. The kit ships with two washable foam filter assemblies, two magnetic vent blockers and a hardware pack to mount directly to CWR or VWM enclosures—dimensions are compact (approximately 5" x 5" x 0.5") and materials include foam, magnetic strips and durable plastic. Magnetic vent blockers can be trimmed to fit varying CWR vent depths for quick customization at installation.
