Middle Atlantic GRK-40-42HLRD – 40SP Gangable Key Rack 42"D

Product Overview

The Middle Atlantic GRK-40-42HLRD is a 40-space gangable key-lock rack enclosure with integrated H-bar cable guides, lever-release door, and 42-inch depth, designed for high-density AV and IT installations where deep equipment and extensive rear cabling require additional internal clearance. As part of the GRK series, this enclosure is built for multi-bay row configurations in broadcast, enterprise AV, and data infrastructure environments. Integrators and procurement teams seeking a 40U deep gangable rack enclosure, a GRK rack with H-bar cable management, or a Middle Atlantic 42-inch deep key-lock rack will find this model appropriate for complex, cable-intensive deployments.

Product Description

The GRK-40-42HLRD provides 40 rack spaces at a 42-inch internal depth, accommodating large network switches, deep AV processors, UPS units, and other equipment that exceeds the depth of standard 27- or 30-inch cabinets. The additional depth also creates substantial rear cable dressing space, reducing the need for external cable management accessories. Integrated H-bar cable guides provide structured vertical pathways for power and signal cables, factory-installed inside the enclosure frame. The lever-release door gives fast, tool-free front access, and the key-lock mechanism provides physical security in shared or access-controlled equipment rooms. Gangable construction allows this unit to be directly coupled with adjacent GRK enclosures to form continuous rack rows without gaps or exposed side panels. Rail hardware is 10-32 standard, compatible with the full Middle Atlantic accessory catalog including power distribution, shelving, and blanking panels. Available through Creation Networks, an authorized Middle Atlantic distributor serving AV integrators and IT infrastructure teams.

Frequently Asked Questions

Why would I choose the 42-inch depth over the 30-inch or 36-inch GRK variants?

The 42-inch depth is appropriate when equipment exceeds 28-30 inches of depth, or when rear cable dressing volume is high enough to require the additional clearance without adding separate rear cable management panels.

Can this unit be used as a stand-alone enclosure?

Yes, with the addition of finished side panels. Contact Creation Networks at creationnetworks.net for side panel options and current availability.

Are H-bars removable if not needed?

H-bars are factory-installed but can typically be removed if the installation requires a clear interior. Consult Middle Atlantic documentation or contact creationnetworks.net for guidance.
