Middle Atlantic MRK-4431PROLRD 44SP/31D MULTIBAY MRK LRD
Product Overview
The Middle Atlantic MRK-4431PROLRD is a 44-space, 31-inch deep MRK series rack enclosure configured with Proliant-compatible sliding rails and a lever-release door. This fully integrated solution is designed for AV integrators and IT managers deploying HP ProLiant servers alongside AV infrastructure in the same rack row, eliminating the need for custom rail sourcing and field adaptation.
Product Description
The MRK-4431PROLRD combines the structural foundation of Middle Atlantic's 44U MRK enclosure with factory-installed Proliant rail hardware and the convenience of a lever-release door. The Proliant rail system is engineered to accept HP ProLiant slide-out server chassis without additional adapter hardware, enabling clean side-by-side installation of server equipment and AV distribution gear within a single 31-inch deep enclosure.
The lever-release door (LRD) provides tool-free front access in seconds, critical in hybrid AV/IT environments where both server OS maintenance and AV signal flow checks must be performed frequently by different teams. The door removes fully for bench-wiring and reinstalls with positive retention. Front uprights carry standard 10-32 tapped rail markings for AV equipment placement alongside the Proliant-configured spaces.
MRK series heavy-gauge steel construction with powder-coat finish. Compatible with Middle Atlantic MRK accessory line including blanking panels, cable managers, side panels, and fan trays.
