Middle Atlantic 24SP/32D Multibay WRK LRD - WRK-24-32LRD

Middle Atlantic WRK-24-32LRD 24RU Seismic-Rated Open-Frame Floor Rack

Overview

The Middle Atlantic WRK-24-32LRD is a 24-rack-unit, 32.63-inch-deep open-frame floor rack engineered for deployments where seismic load certification is a hard requirement — think government facilities, data closets in earthquake zones, and commercial installs governed by ASCE 7-10 standards. At 2,500 lbs UL-listed seismic load capacity and a static weight capacity of 10,000 lbs, this is not a spec-sheet number padded for marketing: it is a UL-verified figure. The WRK-24-32LRD ships from USA manufacturing, carries TAA compliance, and is gangable, making it a practical choice for integrators who need to grow rack footprint without ordering a custom enclosure.

At 24.25 inches wide and 48.13 inches tall, the WRK-24-32LRD fits the standard footprint expected in structured wiring closets and security equipment rooms. With 42 inches of usable height (that 24 RU of actual panel space) and 30.75 inches of usable depth, you have enough clearance for full-depth NVRs, UPS units, and patch panels without the rear-door clearance fights common in enclosed cabinets — there is no rear door on this unit by design, which improves airflow and cable access in high-density installs.

Key Features

• 2,500 lb UL-Listed Seismic Load Capacity (ASCE 7-10): This is the spec that separates a compliant installation from a liability. UL listing under ASCE 7-10 means the seismic performance has been independently tested — not just calculated. For AHJ submittals in California, Oregon, and other high-seismic regions, this is the documentation your inspector wants. Floor-standing racks without this rating won't pass commercial seismic review.
• 10,000 lb Static Weight Capacity: The static rating dwarfs any realistic equipment load. A fully populated 24RU rack with redundant UPS, NVRs, and patch panels might reach 800–1,200 lbs. The 10,000 lb ceiling gives you no plausible scenario where the structure becomes the failure point.
• 30.75 in Usable Depth: Covers full-depth server and NVR equipment comfortably. Most 1U–2U NVRs run 14–24 inches deep; full-depth UPS units run up to 28 inches. The 30.75-inch usable space handles both without forced positioning compromises.
• 24 RU Usable Height (42 in): Twenty-four rack units is the right size for a mid-scale security equipment room — enough for an NVR, PoE switches, a patch panel, and a 1U UPS without going to a full 42RU cabinet that dominates smaller rooms.
• 10-32 Rack Rail Threading: The standard for server and AV equipment. You won't encounter cage-nut compatibility issues with any mainstream NVR, switch, or UPS that ships with rack-mount hardware.
• Gangable Design: If your equipment load grows past 24 RU, gang a second WRK unit alongside rather than migrating everything to a larger cabinet. This is a practical operational benefit on phased deployments — add capacity without a forklift swap.
• TAA Compliant, USA-Made: TAA compliance is a gate requirement on federal contracts and many state/municipal bids. The Federal Ops Country of Origin is USA — no trade-compliance risk, no last-minute bid disqualifications on government security projects.
• No Rear Door: Open-frame rear access means cable management, power distribution, and airflow are not constrained by door clearance. In security closets where technicians need frequent rear access for NVR drive swaps or switch uplinks, this is a deliberate design choice worth noting.

Integration & Compatibility

The WRK-24-32LRD accepts standard 19-inch panel-width equipment on 10-32 threaded rails — compatible with rack-mount NVRs, PoE switches, patch panels, UPS units, and cable management accessories from any manufacturer following EIA-310 standards. The gangable design integrates with other WRK-series frames, allowing multi-bay configurations in larger security equipment rooms without custom hardware. For integrators planning a full rack accessory package — blanks, cable managers, power strips — this frame accommodates standard 19-inch accessories throughout its 24 RU of usable height. Review a rack selection guide to confirm depth and RU requirements match your specific NVR and switch stack before ordering.

Frequently Asked Questions

Q: Is the WRK-24-32LRD TAA compliant?

A: Yes. The WRK-24-32LRD carries TAA compliance and is manufactured in the USA, satisfying federal procurement requirements under the Trade Agreements Act.

Q: What is the seismic rating on the WRK-24-32LRD?

A: The WRK-24-32LRD is UL-listed for seismic load capacity at 2,500 lbs per ASCE 7-10. This is an independently tested and listed rating, not a self-certified calculation — relevant for AHJ submittals in seismic zones.

Q: Can the WRK-24-32LRD be ganged to adjacent rack frames?

A: Yes. The WRK-24-32LRD is gangable, allowing you to bolt it alongside other WRK-series frames for expanded bay configurations without the need for custom brackets.

Q: Does the WRK-24-32LRD include a rear door?

A: No. This is an open-frame design with no rear door, which improves rear cable access and airflow. If you need an enclosed rear, Middle Atlantic offers separate door accessories for the WRK series.

Q: What rail thread type does the WRK-24-32LRD use?

A: 10-32 threaded rails — the standard for server, NVR, and AV rack-mount equipment. No cage nuts required for compatible hardware.

Q: What is the maximum static load capacity of the WRK-24-32LRD?

A: The static weight capacity is 10,000 lbs. The UL-listed seismic load capacity is 2,500 lbs. In practice, a fully populated 24RU security equipment stack will not approach either ceiling.
