Middle Atlantic MRK-4436PROLRD – 44SP/36D MRK PRO Rail and LRD

Product Overview

The Middle Atlantic MRK-4436PROLRD is a 44-space, 36-inch-deep multibay configured rack combining Proliant-compatible rails and a lever-release door for direct HP ProLiant server mounting and fast tool-free front access. This is the fully optioned MRK-4436 configuration, making it the right choice for ProLiant-heavy environments where technicians also need frequent door access. The gangable MRK series design supports multi-bay installations across enterprise AV and IT infrastructure.

Product Description

The MRK-4436PROLRD pairs the 44SP/36" MRK enclosure with two high-value options: Proliant-compatible (PRO) rails and a lever-release door (LRD). The PRO rails allow HP ProLiant servers to mount directly in the rack without procuring or installing separate server rail kits, reducing deployment time and simplifying inventory management in ProLiant-standardized environments. The LRD provides one-hand, tool-free front panel access with a simple lever mechanism, significantly reducing the time cost of routine rack servicing in busy equipment rooms. At 44 rack spaces and 36 inches deep, the MRK-4436PROLRD provides capacity for a full stack of servers, networking gear, power distribution, and AV processing equipment in a single bay. The MRK gangable design allows this enclosure to connect side-by-side with other MRK enclosures, building a multi-bay system with consistent front panel alignment. Welded steel construction supports the static loads typical of a fully populated 44SP server deployment. EIA-standard 19-inch rail spacing also accommodates non-ProLiant equipment on the same rails. Middle Atlantic accessories including PDUs, blanking panels, and cable management integrate directly with the MRK frame. Available at creationnetworks.net.

Frequently Asked Questions

What is the difference between MRK-4436PRO and MRK-4436PROLRD?

The MRK-4436PRO includes Proliant-compatible rails but no door. The MRK-4436PROLRD adds the lever-release door (LRD) to the PRO rail configuration.

Does the lever-release door lock?

The LRD latches securely when closed. Consult Middle Atlantic specifications for available locking configurations on the MRK series door.
