Middle Atlantic MRK-4436PRO – 44SP/36D MRK with Proliant Rails
Product Overview
The Middle Atlantic MRK-4436PRO is a 44-space, 36-inch-deep multibay configured rack with factory-installed Proliant-compatible rails for direct HP ProLiant server mounting. Designed for enterprise AV and IT infrastructure, this MRK series enclosure supports high-density server deployments in ganged multi-bay configurations. The PRO rail option eliminates the need for server-specific rail kits, reducing installation time in ProLiant-heavy environments.
Product Description
The MRK-4436PRO combines a 44-space vertical height with a 36-inch depth, striking a balance between vertical capacity and the deeper equipment clearance needed for full-length servers. The Proliant-compatible (PRO) rail system is factory-installed, allowing HP ProLiant servers and compatible equipment to slide directly into the rack without additional hardware procurement or installation steps. At 44 rack spaces, this enclosure provides enough vertical room to house a mix of 1U servers, patch panels, power distribution, and cable management hardware in a single bay. The MRK series gangable design allows this rack to be bolted side-by-side with other MRK enclosures to form a unified multi-bay installation with consistent panel alignment and shared structural support. Welded steel construction maintains frame rigidity under high static loads common in server-dense deployments. EIA-standard 19-inch rail spacing ensures that non-ProLiant equipment also mounts without adapters. The MRK-4436PRO is appropriate for data centers, server rooms, broadcast facilities, and enterprise AV headend rooms where ProLiant servers are the primary compute platform. Middle Atlantic accessories including PDUs, blanking panels, and cable management integrate directly with the MRK frame. Available at creationnetworks.net.
