Middle Atlantic GRK-40-30HLRD 40SP,30"DPGRKW/HORIZ.BARS

Product Overview

The Middle Atlantic GRK-40-30HLRD is a 40-space, 30-inch-deep gangable key-lock rack with integrated H-bar cable management and a low-resistance door (LRD), designed for multi-bay AV and IT installations requiring deeper equipment clearance. The 30-inch internal depth extends compatibility to full-depth enterprise network hardware, large power amplifiers, and high-capacity UPS systems while the H-bar cable management system maintains organized internal cabling across the 40U build. Like all GRK Series units, the GRK-40-30HLRD is engineered to gang flush with adjacent racks for a seamless multi-bay console appearance.

Product Description

The GRK-40-30HLRD is built on a heavy-gauge steel frame with a black finish, providing the structural rigidity required for fully populated 40U equipment loads in permanent professional installations. The 30-inch internal depth accommodates full-depth rackmount hardware across a wide range of AV, broadcast, and IT equipment categories, eliminating the need for depth extender rails or rack reconfigurations. H-bar cable managers are integrated both horizontally between rack units and vertically along the rack interior, providing structured paths for power, audio, video, and data cabling without additional accessories. The low-resistance door (LRD) allows front access with reduced airflow restriction compared to solid panel doors, supporting thermal management in densely populated configurations. The key-lock latch secures the front door against unauthorized access while allowing fast, tool-free entry for authorized personnel. Included gang hardware enables adjacent GRK Series racks to be joined flush, creating the unified multi-bay appearance required in broadcast, control room, and operations center environments. Front and rear 10-32 tapped rails at EIA-310 spacing ensure universal rackmount equipment compatibility. All assembly hardware is included, and the GRK-40-30HLRD is designed for permanent installation. The unit meets UL and ETL listing requirements for North American professional use.

Frequently Asked Questions

How does the GRK-40-30HLRD differ from the GRK-44-24HLRD?

The GRK-40-30HLRD provides 30 inches of internal depth versus 24 inches on the GRK-44-24HLRD, making it suitable for installations with full-depth enterprise networking hardware, large power amplifiers, and rack-mount UPS units. It has 40 rack spaces compared to 44.

What is the benefit of H-bar cable management in a GRK rack?

H-bars create defined horizontal and vertical routing channels inside the rack, eliminating loose cable bundles and reducing interference between signal and power cabling without requiring separately purchased cable managers.

Can this rack be ganged with other GRK units?

Yes. The GRK Series is designed for side-by-side ganging. Gang hardware is included to join adjacent units flush, creating a seamless multi-bay rack system.

Where can I purchase the GRK-40-30HLRD?
