Middle Atlantic DRK Series Rack DRK19-44-42

Middle Atlantic DRK19-44-42 44U Deep Data Rack — Frame Only

Overview

The Middle Atlantic DRK19-44-42 is a 44U, 42-inch-deep floor-standing steel rack built for data centers, security head-end rooms, and mission-critical AV/IT equipment installations where structural integrity, seismic compliance, and raw load capacity are non-negotiable. At 83.49 inches tall with 77 inches of usable height, this frame accommodates even the densest NVR, server, and switch stacks without dead-end compromises. Specified and shipped as a frame-only configuration, it gives integrators a clean starting point for custom panel, shelf, and blanking layouts rather than locking them into pre-configured kits that rarely match real-world deployments. The DRK19-44-42 (often searched as DRK19 44 42) ships domestically from US origin, TAA-compliant, and carries an OSHPD seismic listing — a hard requirement for California healthcare facilities and a differentiator in any seismically active region.

Key Features

• 44 Rack Units / 77 in. Usable Height: 44U of usable space across 77 inches means you can stack a 16-channel NVR, a PoE switch, a UPS, patch panels, and still have room to grow without ordering a second rack. Fewer racks on the floor means simpler cable runs and lower real estate cost in cramped security head-end rooms.
• 2,500 lb UL-Listed Load Capacity: The UL 2500 lb load rating is the number that matters for permitting and insurance documentation — not a marketing claim. Dense security equipment loads (multiple NVRs with drive arrays, switches, battery backups) can push 800–1,200 lbs without effort; this rack handles that with headroom to spare.
• 10,000 lb Static Weight Capacity: The 10,000 lb static capacity confirms the frame's structural design for fully loaded builds with no concern about frame fatigue over years of 24/7 operation. Relevant for permanent installations where the rack stays put and equipment cycles in and out on a multi-year refresh schedule.
• 42 in. Total Depth / 34.85 in. Usable Depth: At 42 inches overall depth with 34.85 inches usable, this rack accommodates deep 1U/2U servers, full-depth UPS units, and cabled NVRs without forcing cable-management gymnastics at the rear. Shallow equipment installs just as cleanly with rear-rail adjustment.
• Seismic Rating — ASCE 7-10 / OSHPD Listed: The OSHPD seismic listing (California's Office of Statewide Health Planning and Development) is one of the most stringent seismic certifications in the industry. If the project is a California hospital, clinic, or any facility subject to OSHPD review, this listing satisfies the structural documentation requirement outright. For non-healthcare projects in seismic zones, ASCE 7-10 compliance covers most AHJ requirements.
• Gangable Design: The DRK series is gangable, meaning multiple units bolt together side-by-side to form a continuous equipment wall. This is the correct approach for large security operations centers or data rooms where 44U per bay isn't enough — gang four bays and you have 176U of continuous, organized rack space without visible gaps or structural weak points at the joints.
• 19 in. EIA-Standard Rails, 10-32 Threading: Standard 10-32 threaded rails accept virtually all 19-inch rack-mount equipment without adapter kits. If you're specifying this alongside managed PoE switches, NVRs, or patch panels from any major vendor, compatibility is a non-issue.
• Rear Door Included: The rear door ships with the rack, providing physical access control to rear cabling and equipment ports — a basic but often overlooked requirement in shared facilities or co-located head-end rooms where the front is locked but the rear is exposed.
• Steel Construction, USA Origin: All-steel construction from a US manufacturing origin supports TAA compliance documentation for government and federally funded projects. The frame's material and build meet the durability expectations for 10+ year installation life without corrosion or structural degradation in climate-controlled environments.
• 30 in. External Width: At 30 inches wide, the DRK19-44-42 fits standard raised-floor tile grids and doorway clearances that a wider enclosure would not. Plan for 36 inches minimum aisle width alongside this rack for proper airflow and service access — standard for any data rack installation.

Integration and Compatibility

The DRK19-44-42 is engineered for integration with the full Middle Atlantic accessory ecosystem — horizontal and vertical cable managers, brush panels, blanking panels, sliding shelves, power distribution units, and mounting rails all attach to the 10-32 threaded rail pattern without modification. The gangable design works with adjacent DRK-series bays using Middle Atlantic gang hardware. This rack pairs directly with rack-mount power distribution units and UPS systems for complete head-end builds. For large-format surveillance deployments feeding multiple NVRs into a centralized rack, a dedicated cable management strategy for the 34.85-inch usable depth is worth planning before installation — rear-to-front cable routing in deep racks without vertical managers becomes a maintenance problem on a 3–5 year timeline.

The rack is not rated for outdoor or wet-location use. It is intended for climate-controlled data, security, or AV head-end rooms. No equipment is included — this is a frame-only SKU. Power distribution, shelving, blanking panels, and cable management are ordered separately.

Frequently Asked Questions

Q: Is the DRK19-44-42 TAA compliant?

A: Yes. The DRK19-44-42 is TAA compliant and manufactured in the USA, making it eligible for GSA schedule and federal procurement projects requiring Trade Agreements Act compliance.

Q: What is the UL-listed load capacity of the DRK19-44-42?

A: The UL-listed load capacity is 2,500 lbs (1,134 kg). The static weight capacity of the frame itself is 10,000 lbs (4,535.9 kg). For permitting and insurance documentation, use the UL-listed figure of 2,500 lbs.

Q: Is the DRK19-44-42 seismic rated?

A: Yes. It carries an OSHPD seismic listing (California Office of Statewide Health Planning and Development) and meets ASCE 7-10 seismic load requirements — one of the most stringent seismic certifications applicable to rack systems. This satisfies AHJ documentation requirements in seismically active regions and is a hard requirement for California healthcare facility installations.

Q: What rack unit and depth configurations does this model provide?

A: The DRK19-44-42 provides 44U of rack space (77 inches of usable height) in a 42-inch total depth frame (34.85 inches usable depth). External dimensions are 83.49 in. H × 30 in. W × 42 in. D.

Q: Does the DRK19-44-42 include shelving, power strips, or cable management?

A: No. This is a frame-only configuration. No shelves, power distribution units, blanking panels, or cable managers are included. These must be ordered separately.

Q: Can multiple DRK19-44-42 units be ganged together?

A: Yes. The DRK series supports gangable installation, allowing multiple bays to be bolted side-by-side to form a continuous rack wall. This is the recommended approach for large security operations centers or data rooms requiring more than 44U of capacity.

The spec that defines where the DRK19-44-42 belongs on a project is the OSHPD seismic listing. I've specified this rack in security head-end rooms for California hospital expansions where the structural engineer requires OSHPD rack documentation before the room closes — and the DRK19-44-42 delivers that paperwork without a custom engineering study. The 2,500 lb UL load rating combined with 44U of usable space handles a dense NVR + switch + UPS build with margin left over.

Technical Highlights:

• OSHPD / ASCE 7-10 Seismic Certification: Satisfies AHJ structural documentation in California healthcare and high-seismic-zone projects outright — no supplemental engineer letter required in most jurisdictions.
• 2,500 lb UL-Listed Load / 10,000 lb Static Capacity: The UL figure is what goes on permit drawings; the 10,000 lb static number tells you the frame's actual structural margin. Dense security builds topping 1,200 lbs loaded are well within range.
• 34.85 in. Usable Depth: Accommodates full-depth 2U NVRs, tower UPS in a rack-mount kit, and rear-cabled patch panels simultaneously — the real-world test most spec sheets skip.

Deployment Considerations:

• Frame-only SKU: budget separately for cable managers, blanking panels, PDUs, and shelves before submitting the BOM — the rack ships as a bare frame.
• At 30 inches wide, door clearance is typically fine, but verify your raised-floor or slab cutout dimensions before delivery on retrofit jobs — 30W × 42D requires more floor prep than a standard 24-inch-deep enclosure.

The DRK19-44-42 is the right call for permanent, high-density security and IT head-end rooms in California healthcare facilities, government buildings, and any project where seismic documentation is a permit prerequisite — not just a nice-to-have.
