Product Overview

The Middle Atlantic VFD-21 is a 21-space vented front door with a universal black finish. Designed for AV integrators and IT managers who need a finished front door on rack enclosures while maintaining airflow for heat-generating equipment.

Product Description

The VFD-21 vented front door provides 21U of rack enclosure coverage with perforated or louvered venting that allows passive and active airflow to pass through the front panel. This is the correct door choice when rack equipment generates significant heat and requires front-to-rear or bottom-to-top airflow that a solid door would obstruct. The universal black finish coordinates with standard equipment rack aesthetics across multiple rack brands and configurations. At 21U, the VFD-21 is suited for mid-height enclosures common in AV equipment rooms, IDF closets, and network infrastructure deployments.
