Middle Atlantic GRK-52-30HLRD – 52RU GRK Gangable Rack with H-Bars

Product Overview

The Middle Atlantic GRK-52-30HLRD is a 52 rack space welded gangable rack with 30 inches of depth, horizontal cable management H-bars, and a less-rear-door configuration for open rear access or a separately specified door. The GRK Series is built for narrow multi-bay equipment rows optimized for high-density video cable bundles, making it a standard choice for broadcast, production, and large commercial AV installations. With a 1,500 lb. weight capacity and UL-2416 listing, it carries full equipment loads in continuous ganged rows.

Product Description

The GRK Series is a versatile welded gangable rack engineered for installations where a narrow multi-bay footprint must still manage high-density video and signal cabling. The GRK-52-30HLRD provides 52 rack spaces of mounting height at 30 inches of depth, with numbered rackspace increments that simplify and speed equipment installation against the rack elevation drawing.

This configuration includes horizontal cable management bars for tie-and-slide lacing, giving installers defined support and tie-off points across the rear of the enclosure. The fully open top and bottom allow straight vertical cable runs into the rack, and finished edges at both openings improve appearance while preventing cable chafing on high-count bundles. Integrators can choose horizontal or vertical lacing strategies to match the cabling design.

Construction details support long service life in commercial deployment: a solid frame top and bottom strengthens the welded structure, grounding and bonding studs come standard top and bottom for code-compliant bonding, and the enclosure is finished in a durable black textured powder coat. The rack is UL-2416 listed (NWIN) and rated for a 1,500 lb. equipment load.

The LRD designation means this model ships less rear door, suited to racks that back up to a service aisle or that will receive a separately specified GRK door. The universal hinged GRK door family installs with left or right swing, front and back, with solid, vented, and cupboard-style beveled door options available.
