Middle Atlantic MW-CLVRD-44 44U Split Vented Rear Door for Open-Frame Rack Systems

Overview

The Middle Atlantic MW-CLVRD-44 is a 44U split vented rear door designed to close out the back of Middle Atlantic MRK, WRK, or VRK series open-frame racks — giving you a finished, ventilated enclosure without blocking airflow in dense equipment deployments. At 78.32 inches tall and 19.2 inches wide, it covers a full 44-rack-unit column from floor to top rail. The split design means you can open one half at a time, which matters in tight equipment rooms where swinging a single full-height door requires clearance you may not have. If you're building out a rack in a closet, IDF, or against a wall, the MW-CLVRD-44 (often searched as MW CLVRD 44) eliminates the clearance problem without sacrificing rear access.

This is an accessory component for existing Middle Atlantic rack infrastructure — not a standalone enclosure. Verify your base rack is an MRK, WRK, or VRK series before ordering.

Key Features

• 44U height (78.32 in / 198.9 cm): Covers the full rear opening of a 44U rack column. If your rack height doesn't match, this door will not fit — confirm RU count before purchasing.
• Split vented design: Two independently operable door halves let you access upper or lower equipment without opening the entire rear. In a deep equipment room with limited rear clearance, this is the practical choice over a single-panel door.
• Vented panel construction: Airflow passes through rather than being blocked, which keeps rear-mounted equipment from running hot. Relevant if you're housing switch stacks, patch panels with active cable management, or any equipment whose exhaust faces the rear door.
• 19.2 in (48.8 cm) width: Standard rack-width footprint. Fits the MRK, WRK, and VRK base frames without modification.
• 3.01 in (7.7 cm) depth: Minimal protrusion from the rack rear — relevant when calculating total rack depth in constrained spaces or when planning cable ladder clearance behind the rack.
• Integrated handles: Both door halves include handles, so technicians can open either panel bare-handed without needing a key or tool. Speeds up routine maintenance and cable dress access.
• Shipping weight 38 lbs (17.2 kg): Plan for two-person installation when lifting into position on a fully populated rack. The door is substantial — don't try to hang it solo on a rack that's already loaded.

Integration and Compatibility

The MW-CLVRD-44 is confirmed compatible with Middle Atlantic MRK, WRK, and VRK series open-frame racks in the 44U configuration. It is not a universal fit — Middle Atlantic's rack door system is series- and RU-specific. If your installation uses a different base series or a different rack unit count, a different door model is required. Cross-reference your rack's series designation and RU count against the MW-CLVRD-44 spec before ordering to avoid a return.

For rack planning and accessory selection across the Middle Atlantic product line, confirm compatibility at the series level. When deploying in rack enclosure environments, coordinate with your cable management and PDU strategy before finalizing door selection — rear door depth and ventilation pattern affect airflow and rear-cable routing. If you're evaluating rack accessories beyond the door itself, consider blanking panels, side panels, and power distribution to complete the enclosure build. For guidance on rack density and thermal management in AV and security equipment rooms, review a rack planning guide before committing to a door configuration.

Frequently Asked Questions

Q: What rack series is the MW-CLVRD-44 compatible with?

A: The MW-CLVRD-44 is compatible with Middle Atlantic MRK, WRK, and VRK series open-frame racks in the 44U configuration. It is not confirmed compatible with other rack series or rack unit counts — verify your base rack before ordering.

Q: Does the MW-CLVRD-44 obstruct rear airflow?

A: No. The door features a vented panel design that allows airflow to pass through, making it suitable for equipment-dense deployments where rear exhaust clearance is important.
