Middle Atlantic 44SP 36D GRK W/hbars LRD - GRK-44-36HLRD

Middle Atlantic GRK-44-36HLRD 44RU Broadcast Floor Rack with Horizontal Bars and LRD

Overview

The Middle Atlantic GRK-44-36HLRD is a 44-rack-unit, 36-inch-deep broadcast-grade floor rack built for installations where structural integrity, load capacity, and long-term serviceability are non-negotiable. At 80 inches tall and rated for 1,500 lbs of equipment weight, this is the rack you spec when a standard relay rack simply won't cut it — think broadcast master control rooms, large-format AV integration bays, security operations centers, or enterprise server/NVR consolidation rooms. GRK-44-36HLRD ships from US manufacturing and carries TAA compliance, making it eligible for federal and government-contract deployments where country-of-origin documentation is required.

The GRK series from Middle Atlantic racks and enclosures targets integrators who need a open-frame rack that ships with horizontal management bars (hbars) and a Lacing Rod Dual (LRD) pre-installed — cutting down field assembly time on dense cable runs. If you're building out a floor standing rack for a multi-NVR surveillance backend or broadcast infrastructure, the combination of 44RU capacity and 36-inch depth handles most 2U–4U appliances without forcing you into a custom-depth enclosure.

Key Features

• 44 Rack Units / 80-inch height: Enough vertical real estate to consolidate a full surveillance NVR stack, patch panels, UPS units, and cable management in a single rack footprint — reducing floor space consumption versus splitting across two shallower units.
• 36-inch usable depth (91.4 cm): Accommodates deep server-class appliances, broadcast recorders, and enterprise NVRs that regularly run 28–32 inches in chassis depth. Shallow racks force cable-bend compromises; at 36 inches you have clearance for rear connectors and airflow management behind the equipment.
• 1,500 lb static weight capacity (680.4 kg): Engineered for fully populated high-density builds. A 44RU rack loaded with 2U appliances at roughly 20–30 lbs each still has significant headroom before approaching this limit — meaning you're not engineering around the rack's structural limits when you load it out.
• Horizontal management bars (hbars) included: Pre-installed horizontal cable managers eliminate the extra SKU and field-install step of sourcing cable management separately. On a 44RU build with dozens of patch cables, structured horizontal management is the difference between a serviceable rack and a cable nest in 18 months.
• Lacing Rod Dual (LRD) included: The LRD provides a rear vertical lacing path for power and signal cables, keeping them separated from the equipment faces and making future adds/moves cleaner. This is standard practice on broadcast and security operations center builds — having it ship pre-configured saves a field step.
• No rear door — open-frame configuration: Intentional design choice for environments where rear cable access needs to be unrestricted and airflow is managed by room CRAC/CRAH systems rather than rack-internal fans. If your installation requires a rear door for dust control or physical security, spec a cabinet variant instead.
• TAA compliant, manufactured in the USA: Federal procurement, GSA schedule orders, and DoD deployments require TAA-compliant equipment with verifiable country of origin. The GRK-44-36HLRD satisfies both — cULus listed and USA-origin documented.

Integration and Compatibility

The GRK-44-36HLRD follows standard 19-inch EIA rack rail spacing, making it compatible with virtually any rack-mount equipment — network video recorders, managed PoE switches, KVM systems, patch panels, and UPS units. The 36-inch depth is particularly well-suited to pairing with deep-chassis NVRs common in enterprise surveillance deployments, where 24- or 32-bay storage appliances often push past 28 inches. For teams building out full rack systems, pair this with rack PDUs and power distribution sized to the total draw of your equipment load — the 1,500 lb capacity means you can plan for a fully populated build without structural concerns driving your appliance selection.

The GRK 44 36HLRD (often searched as GRK 44 36HLRD) is also a fit for broadcast facilities, post-production suites, and NOC environments where open-frame access and structured cable management matter more than physical enclosure security.

Frequently Asked Questions

Q: Is the GRK-44-36HLRD TAA compliant?

A: Yes. The GRK-44-36HLRD is TAA compliant with a Federal Operations country of origin of USA, making it eligible for federal procurement and GSA schedule orders.

Q: What is the weight capacity of the GRK-44-36HLRD?

A: The GRK-44-36HLRD is rated for a static weight capacity of 1,500 lbs (680.4 kg), accommodating fully populated high-density equipment loads without structural limitations.

Q: Does the GRK-44-36HLRD include a rear door?

A: No. The GRK-44-36HLRD is an open-frame rack with no rear door. This is by design for environments relying on room-level cooling and requiring unrestricted rear cable access. If a rear door is required, a cabinet-style enclosure would be the appropriate alternative.

Q: What rack units and depth does the GRK-44-36HLRD provide?

A: The GRK-44-36HLRD provides 44 rack units of usable vertical space and 36 inches (91.4 cm) of usable depth, standing 80 inches (203.2 cm) tall overall.

Q: What cable management accessories are included with the GRK-44-36HLRD?

A: The GRK-44-36HLRD ships with horizontal management bars (hbars) and a Lacing Rod Dual (LRD) pre-installed, providing both horizontal and vertical cable routing paths out of the box.

Q: What is the shipping weight of the GRK-44-36HLRD?

A: The GRK-44-36HLRD has a shipping weight of 135 lbs (61.2 kg).

The spec that matters most on the GRK-44-36HLRD isn't the RU count — it's the 1,500 lb weight capacity paired with the 36-inch depth. Most open-frame racks in the 44RU class cap out at 1,000–1,200 lbs, which starts to bite when you're populating with high-density storage appliances, broadcast recorders, or stacked UPS units. At 1,500 lbs, the GRK-44-36HLRD gives you room to fully load 44 rack units without engineering around the rack's structural ceiling.

Technical Highlights:

• 1,500 lb capacity: Supports full population of dense 2U–4U appliances — surveillance NVRs, broadcast recorders, managed switches — without approaching structural limits, which matters when a fully loaded rack can easily exceed 800–1,000 lbs.
• 36-inch depth: Specifically sized for deep-chassis equipment. Enterprise NVRs and server appliances routinely run 28–32 inches; at 36 inches you maintain rear cable clearance and proper airflow management behind the equipment plane.
• TAA compliant, USA origin: Documented country of origin for federal procurement workflows — no additional COO certification required for GSA or DoD orders, which matters if you're bidding government security or broadcast facility contracts.

Deployment Considerations:

• The open-frame design (no rear door) means your facility HVAC or CRAC system is responsible for rack thermal management — plan your airflow paths before populating, especially on fully loaded builds where equipment exhaust can stack up in a 44RU column.
• At 135 lbs shipping weight for the empty rack, factor in a two-person lift and appropriate floor loading for the installation site — fully populated at 1,500 lbs, you need a structural floor assessment in older buildings.

The GRK-44-36HLRD is the right rack for broadcast master control rooms, large-format security operations centers, and federal facility integrations where TAA compliance, deep-chassis equipment clearance, and long-term structural reliability are all hard requirements on the same RFP line.
