Middle Atlantic DRK19-44-42PRO 44U Deep Data Rack — Seismic-Rated, 42-Inch Depth
Overview
The Middle Atlantic DRK19-44-42PRO is a 44-rack-unit, 42-inch-deep floor-standing steel data rack built for environments where seismic compliance, structural integrity, and long-term serviceability are non-negotiable. Standing 83.49 inches tall with a 30-inch overall width, it provides 77 inches of usable height and 34.85 inches of usable depth — enough clearance to house deep servers, NVR appliances, UPS units, and patch infrastructure without compromise. This is a frame-only configuration, giving integrators and IT architects full flexibility to populate it with their own rails, shelves, and cable management. If you're specifying racks for a healthcare facility, government project, or any installation in a seismic zone, the DRK19-44-42PRO (often searched as DRK19 44 42PRO) belongs on your shortlist.
Sourced factory-new from Middle Atlantic's rack and enclosure line, this unit carries TAA compliance and an OSHPD seismic listing — two credentials that frequently appear as hard requirements on public-sector and healthcare bid sheets. It is manufactured in the USA.
Key Features
- 44 Rack Units / 77-inch Usable Height: Full 77 inches of usable space in a floor-standing rack means you can stack a dense NVR stack, managed PoE switches, patch panels, and a 2U UPS without running out of room. Few 44U frames at this depth deliver that combination.
- 42-Inch Total Depth / 34.85-Inch Usable Depth: Deep enough to house extended-depth servers and 2-post-style appliances flush, while the 34.85-inch usable measurement gives you honest cable bend radius behind rear-mounted gear — consult your cable management accessories plan before finalizing rail position.
- 2,500 lb UL-Listed Load Capacity: UL-verified at 2,500 lbs static floor load. That's not a marketing figure — it's a tested, listed value relevant to structural engineers signing off on equipment room drawings.
- 10,000 lb Weight Capacity (Frame): The frame itself is rated to 10,000 lbs, which matters during transport and staging in high-density deployments where multiple racks are moved together.
- OSHPD Seismic Listing / ASCE 7-10: Compliance with OSHPD (Office of Statewide Health Planning and Development) and ASCE 7-10 seismic load standards means this rack meets California hospital AHJ requirements and is accepted on most government seismic-zone submittals. This is not a self-certified claim — it's a listed approval.
- TAA Compliant, USA-Made: Manufactured domestically and TAA-compliant, satisfying Federal Acquisition Regulations on government contracts where country-of-origin documentation is required.
- Cage Nut Rail System: Standard 19-inch cage nut rails accept virtually all rack-mount gear without proprietary adapters. Square-hole toolless rails are NOT included — budget for the appropriate rail kit separately if needed.
- Rear Door Included: Shipped with a rear door — relevant for airflow management and physical security of rear-panel connections in open equipment rooms.
- Gangable Design: Confirmed gangable, allowing side-by-side rack arrays to be bolted together for multi-rack deployments without gaps or alignment issues.
Integration and Compatibility
The DRK19-44-42PRO is a frame-only product — no rails, shelves, or blanks are included. All standard 19-inch rack-mount equipment fits the cage nut rail system. For network video recorders, managed switches, or servers requiring tool-less slide rails, verify the specific slide rail kit compatibility against the 34.85-inch usable depth before ordering. The 30-inch overall width is wider than a standard 24-inch footprint rack; verify floor plan clearances for your equipment room layout. Not available for international shipment.
Frequently Asked Questions
Q: Is the DRK19-44-42PRO TAA compliant?
A: Yes. The DRK19-44-42PRO is TAA compliant and manufactured in the USA, satisfying Federal Acquisition Regulation requirements for government procurement.
Q: What is the UL-listed load capacity of the DRK19-44-42PRO?
A: The UL-listed static load capacity is 2,500 lbs (1,134 kg). The frame weight capacity is rated to 10,000 lbs (4,535.9 kg).
Q: Does the DRK19-44-42PRO meet seismic requirements for California hospital installations?
A: Yes. It carries an OSHPD listing and complies with ASCE 7-10 seismic load standards, which are required for California OSHPD-regulated healthcare facilities.
Q: What rail type does the DRK19-44-42PRO use?
A: Standard 19-inch cage nut rails. Tool-less or square-hole rails are not included — order the appropriate rail kit separately based on your equipment requirements.
Q: Is a rear door included with the DRK19-44-42PRO?
A: Yes, a rear door is included. No front door is specified in the product configuration — this is a frame-only build.
Q: What is the usable depth of the DRK19-44-42PRO?
A: Usable depth is 34.85 inches (88.5 cm), within a 42-inch total rack depth. Plan cable management to stay within this clearance for rear-mounted equipment.
The spec that sets the DRK19-44-42PRO apart in competitive bids isn't the 44U height or the 42-inch depth — it's the OSHPD listing backed by ASCE 7-10 seismic compliance. When you're deploying security or network infrastructure in a California hospital or any AHJ that requires a listed seismic rack, this is the document your structural engineer needs, and most commodity racks simply don't have it.
Technical Highlights:
- 2,500 lb UL Load Capacity: Listed — not estimated. On a fully loaded 44U rack with NVRs, switches, and UPS gear, this gives the structural engineer a verified number to put on the drawing, not a spec-sheet guess.
- 34.85-Inch Usable Depth: Within a 42-inch overall frame, you retain 34.85 inches of clear depth. Most extended-depth 2U servers and 4U NVR appliances fit without forcing rear cable trays to compete for space — but measure your deepest unit before finalizing rail position.
- Cage Nut Rails, Frame-Only Config: The frame-only configuration keeps the DRK19-44-42PRO procurement-flexible — you're not paying for bundled blanks or shelves you'll strip out anyway on a custom build. Cage nut compatibility is universal across the vendor mix typical in security/AV head-end rooms.
Deployment Considerations:
- Overall width is 30 inches — wider than a standard 24-inch rack footprint. Verify your equipment room floor plan and aisle clearances before delivery; this unit ships at 267 lbs and requires appropriate staging and lift equipment.
- This is a frame-only product: no rails, shelves, front door, or blanks are included. Budget for cage nut rail kits, PDUs, and cable management as separate line items, and confirm slide rail compatibility against the 34.85-inch usable depth for any server or appliance with fixed-length rails.
The DRK19-44-42PRO is the right specification for healthcare equipment rooms, state and federal government data closets, and any project where the AHJ requires a signed-off seismic rack listing rather than a self-certified claim — particularly in California OSHPD-regulated facilities where the OSHPD number is a hard submittal requirement.
