Middle Atlantic GRK-52-36HLRD – 52U 36 in. Deep Broadcast Rack, H-Bars

Product Overview

The Middle Atlantic GRK-52-36HLRD is a 52-space, 36-inch-deep GRK Series broadcast rack supplied with H-bar cable management and configured less rear door, built for high-density broadcast and enterprise AV installation. The gangable key-lock frame lets integrators join multiple units into continuous rack rows for equipment-room and head-end deployments. With 91 inches of usable mounting height, it is one of the highest-capacity configurations in the GRK line. The less-rear-door configuration suits installations where racks are placed against open cable chases or where a separate rear access solution is specified.

Product Description

The GRK-52-36HLRD pairs maximum vertical capacity with a 36-inch interior depth that accepts deep servers, UPS systems, and large AV matrix switchers without rail extenders. H-bar horizontal cable guides are integrated at multiple positions within the rack height, giving structured routing paths for patch cabling, fiber, and signal runs between equipment bays during commercial deployment. Because the unit ships less rear door, integrators can leave the rear open for row-based cable chase access or add a Middle Atlantic rear door later if the project requires enclosed security. The GRK gangable frame joins adjacent racks with minimal gap using the key-lock ganging system, producing uniform rack rows for broadcast plant and network operations builds. Welded steel construction keeps the rails square under a full 52 spaces of loaded equipment, which matters when heavy amplifiers and power distribution sit low in the bay. Standard 10-32 tapped rails follow EIA-310, so off-the-shelf rack shelves, lacing bars, and vent panels mount without adapters. For AV designers, the combination of depth, H-bar management, and gangability simplifies signal-flow documentation and day-two service in large systems. The GRK-52-36HLRD is available now from Creation Networks, alongside the full Middle Atlantic rack and enclosure line.

Frequently Asked Questions

Is the GRK-52-36HLRD compatible with standard 19-inch rack equipment?

Yes. The 10-32 tapped rails follow the EIA-310 standard, so any standard 19-inch rack-mount equipment, shelves, and panels install directly.

Why does this rack ship without a rear door?

The LRD (less rear door) configuration is intended for ganged rack rows, cable-chase installations, or projects where a specific Middle Atlantic rear door or access solution is ordered separately.

Can I add a rear door later?

Yes. Middle Atlantic offers compatible rear doors for the GRK series. Contact Creation Networks to match the correct door to a 52-space, 36-inch-deep frame.

How many GRK racks can be ganged together?

GRK frames gang side-by-side using the key-lock system; row length is limited by room layout and floor loading rather than the frame itself. Creation Networks can assist with multi-bay configuration planning.

Does the 36-inch depth support full-depth servers and AV processors?

Yes. The 36-inch interior depth accommodates deep enterprise servers, UPS units, and large matrix switchers commonly used in broadcast and commercial AV integration.

What warranty applies to this rack?

The GRK-52-36HLRD is covered by Middle Atlantic's manufacturer warranty. Contact Creation Networks for current warranty terms and registration details.

Can Creation Networks help with rack elevation and system design?

Yes. Creation Networks supports integrators and facility teams with product selection, accessory matching, and pre-sale design questions for Middle Atlantic rack systems.
