Middle Atlantic GRK-48-36HLRD – 48RU GRK Gangable Rack, 36" Deep

Product Overview

The Middle Atlantic GRK-48-36HLRD is a 48 rack space welded gangable rack with 36 inches of depth, factory-installed horizontal cable management H-bars, and a less-rear-door configuration for open rear service access or a separately specified GRK door. It is engineered for narrow multi-bay equipment rows that must manage high-density video cable bundles in broadcast, production, and large commercial AV installations. A 1,500 lb. weight capacity and UL-2416 listing make it ready for fully loaded equipment bays in commercial deployment.

Product Description

The GRK Series is a versatile welded gangable rack chosen when a narrow multi-bay footprint must still carry high-density video and signal cabling with a choice of horizontal or vertical lacing. The GRK-48-36HLRD pairs 48 rack spaces with a 36-inch depth, a middle-depth option in the line that clears most AV processors, switchers, and amplifier chassis while keeping the rack row footprint shallower than 42-inch configurations.

Horizontal cable management bars support tie-and-slide lacing across the rear of the enclosure, keeping bundles supported and rear-panel connections free of strain during AV integration and later service. The fully open top and bottom permit straight vertical cable runs into the rack from overhead pathways or raised floors, and finished edges at both openings prevent cable chafing while presenting a clean appearance.

The structure uses a solid frame top and bottom for added strength, carries a 1,500 lb. weight capacity, and is finished in a durable black textured powder coat. Grounding and bonding studs are standard top and bottom for code-compliant bonding, the enclosure is UL-2416 listed (NWIN), and numbered rackspace increments simplify and speed equipment installation against the rack elevation.

As an LRD model, this rack ships less rear door for service-aisle layouts or pairing with a door from the universal hinged GRK door family, which installs with left or right swing on front or back and is offered in solid, vented, and cupboard-style beveled versions.

Technical Specifications

Frequently Asked Questions

What do the H and LRD designations mean on this rack?

H indicates factory-installed horizontal cable management bars for tie-and-slide lacing; LRD means the rack ships less rear door, for open rear access or a separately purchased GRK door.

Which doors fit the GRK-48-36HLRD?

48RU doors from the universal hinged GRK family fit this rack, including the GFRD-48 solid door and GLVFRD-48 large-perforation vented door, each installing with left or right swing on front or back.

Why choose 36-inch depth over 30 or 42 inches?

The 36-inch depth clears most AV processors, video switchers, and amplifiers with full rear cable bend radius while keeping the equipment row shallower than a 42-inch rack, which matters in space-constrained equipment rooms.

How is cabling routed into and through the rack?

The fully open top and bottom allow straight vertical cable runs from overhead tray or raised floor, with finished edges that prevent chafing, while H-bars carry horizontal lacing across the rear.

Can this rack be ganged into a multi-bay row?

Yes. The GRK Series is a gangable platform; racks of matching height and depth bolt side by side into continuous equipment bays for larger installations.

Does it meet grounding and safety listing requirements?

Yes. Grounding and bonding studs are standard top and bottom, and the rack is UL-2416 listed (NWIN) for AV and IT equipment enclosures.

What warranty and configuration support are available?

Middle Atlantic racks carry the manufacturer's warranty through Legrand AV. Creation Networks is an authorized dealer and assists with rack elevations, door and accessory selection, and project quotes.
