Middle Atlantic GRK-48-42HLRD – 48RU GRK Broadcast Rack with H-Bars

Product Overview

The Middle Atlantic GRK-48-42HLRD is a 48 rack space GRK Series broadcast rack with 42 inches of interior depth, integrated cable management H-bars, and a less-rear-door configuration for installations that pair the enclosure with a separately specified rear door or open rear access. It is built for broadcast studios, large AV equipment rooms, and multi-rack head-end installations where deep-chassis equipment and high-count cabling must stay organized and serviceable. The gangable GRK platform lets integrators join multiple bays side by side as system requirements grow.

Product Description

The GRK Series is Middle Atlantic's broadcast rack line, engineered for the density, depth, and cable loads found in broadcast, production, and enterprise AV infrastructure. The GRK-48-42HLRD delivers 48 rack spaces at a 42-inch depth, one of the deepest configurations in the line, with the clearance needed for broadcast processing gear, large AV switching frames, and deep server chassis along with full rear cable bend radius.

The H-bar configuration places horizontal cable management bars at defined intervals within the rack, giving installers dedicated routing and tie-off points along the rear of the enclosure. H-bars keep cable bundles supported, reduce strain on rear-panel connectors, and make high-count structured cabling installations faster to dress, document, and service over the life of the system.

This model ships less rear door, which suits deployments where racks back up to a service corridor, where open rear access is preferred, or where a specific Middle Atlantic rear door is added separately. Compatible 48RU doors for GRK racks include solid and large-perforation vented options, allowing the thermal and security configuration to match the room design.

Gangable construction allows multiple GRK racks of matching height and depth to bolt together into a continuous equipment bay for commercial deployment at scale.

Technical Specifications

Frequently Asked Questions

What does the HLRD suffix mean on this GRK rack?

H indicates the rack includes horizontal cable management H-bars, and LRD means it ships less rear door. This configuration is common where racks back up to a service aisle or where a specific rear door is added separately.

Can I add a rear door later?

Yes. Middle Atlantic offers 48RU doors for GRK racks, including the GFRD-48 solid door and GLVFRD-48 large-perforation vented door. Creation Networks can match the correct door to your thermal and security requirements.

What are H-bars and why do they matter in AV integration?

H-bars are horizontal cable support bars positioned at intervals inside the rack. They give installers tie-off points that keep cable bundles supported, protect rear-panel connections from strain, and keep high-count installations serviceable.

Can the GRK-48-42HLRD be ganged with other GRK racks?

Yes. GRK racks of matching height and depth bolt together side by side to form continuous multi-bay rows. Matching dimensions keep the bay flush and consistent.

Is 42 inches of depth necessary for broadcast equipment?

Deep broadcast processors, router frames, and servers frequently exceed the capacity of standard-depth racks. The 42-inch depth provides chassis clearance plus proper rear cable bend radius for dense terminations.

What warranty covers this rack?

Middle Atlantic racks carry the manufacturer's warranty through Legrand AV. Creation Networks is an authorized dealer, so every unit qualifies for full factory warranty support.

Does Creation Networks help with multi-rack room layouts?

Yes. Our commercial AV team supports integrators with rack elevations, ganged bay planning, accessory selection, and volume project quotes.
