Vertiv CMRX-52U24-W-1224 52U Open-Frame Cabinet Rack Enclosure
Overview
The Vertiv CMRX-52U24-W-1224 is a 52U open-frame rack cabinet finished in Winter White — a purpose-built mounting structure for IT, networking, and physical security equipment in environments where aesthetics or facility standards call for a lighter color profile. At 52U of usable space, it accommodates dense equipment stacks without requiring a full-depth server room enclosure. The CMRX-52U24-W-1224 ships with #12-24 tapped 3/8" square (M6-compatible) rails, the industry-standard hole pattern for mounting rackmount gear — meaning your switches, patch panels, NVRs, and 1U appliances mount without adapter hardware. UL2416 listing confirms independent third-party evaluation to the standard for information technology equipment racks and enclosures, a common requirement for data center and commercial building compliance sign-offs. RoHS II compliance covers hazardous substance restrictions, relevant for facilities operating under EU directives or green-building procurement policies.
Key Features
- 52U Capacity: Provides room for high-density equipment stacks — enough vertical space for a full NVR array, patch panels, PoE switches, and power distribution in a single structure without floor-plan sprawl.
- #12-24 Tapped Rails with 3/8" Square (M6) Pattern: Standard hole geometry means off-the-shelf cage nuts and rack screws fit without sourcing proprietary hardware — saves time during initial rack builds and future equipment swaps.
- Winter White Finish: Suits open-plan offices, security operations centers, or facilities where black enclosures would conflict with interior standards. Available in Black for environments where that is preferred — confirm color at order time.
- UL2416 Listed: Independent safety certification to the rack and enclosure standard — a prerequisite for compliance in many commercial construction and data center specifications.
- RoHS II Compliant: Meets the EU Restriction of Hazardous Substances Directive (recast), supporting green procurement requirements and facilitating import into regulated markets.
- 20x 3.5" × 5" 1/4-Turn D-Rings Included: Cable management D-rings ship in the box at a count of 20 — enough to dress a fully populated rack without a separate cable management order. The 1/4-turn attachment means no tools needed to install or reposition them during cabling runs.
Integration & Compatibility
The CMRX-52U24-W-1224 is compatible with standard EIA-310 rackmount equipment using #12-24 or M6 fasteners. The 24-inch width accommodates standard 19-inch rack-mount equipment — the universal form factor for network switches, network video recorders, patch panels, KVM units, and 1U/2U server appliances. Pair with a Vertiv power distribution unit or compatible PDU from the Vertiv rack infrastructure line for an integrated power and mounting solution. For surveillance infrastructure deployments, this cabinet suits NVR and switch consolidation in PoE switch and storage-dense rack builds where open-frame access simplifies cable routing and airflow management. Review the available rack enclosure options if a fully enclosed cabinet with locking doors is required for your site security policy.

Frequently Asked Questions
Q: What rail hole pattern does the CMRX-52U24-W-1224 use?
A: The CMRX-52U24-W-1224 uses #12-24 tapped rails with a 3/8-inch square hole pattern, which is also compatible with M6 hardware. This is the standard EIA-310 pattern used by virtually all 19-inch rackmount equipment.
Q: Is the CMRX-52U24-W-1224 available in colors other than White?
A: Yes. The CMRX cabinet line is available in both Black and Winter White finishes. The CMRX-52U24-W-1224 specifically designates the Winter White (W) variant. Confirm color when ordering if your facility has specific requirements.
Q: What safety certifications does the CMRX-52U24-W-1224 carry?
A: The CMRX-52U24-W-1224 is UL2416 listed (the safety standard for IT equipment racks and enclosures) and RoHS II compliant for hazardous substance restrictions.
Q: Are cable management accessories included with the CMRX-52U24-W-1224?
A: Yes. The unit ships with 20 units of 3.5-inch by 5-inch 1/4-turn D-rings for cable management, along with rack mount hardware. No additional cable ring order is required to dress a standard rack build.
Q: What rack unit sizes are available in the CMRX cabinet family?
A: The CMRX family is available in 45U, 52U, and 59U configurations. The CMRX-52U24-W-1224 is the 52U model in a 24-inch-wide footprint with Winter White finish.
When I spec out a rack build for a security operations center or a distributed NVR closet, the mounting hardware matters more than buyers often expect. The CMRX-52U24-W-1224 uses #12-24 tapped rails with 3/8-inch square holes — that dual-standard geometry (also M6-compatible) means your team is not hunting for proprietary cage nuts the day of installation. The 52U height is the sweet spot for a surveillance infrastructure stack: you can rack a 32- or 64-channel NVR, a managed PoE switch, a patch panel, and a UPS in a single cabinet with vertical space to spare for future expansion.
Technical Highlights:
- #12-24 / M6 Tapped Rails: Dual-standard rail geometry fits the full range of commercial rackmount equipment without adapter plates — a real time-saver when you are commissioning a mixed-vendor stack of NVRs, switches, and power gear.
- 20x 1/4-Turn D-Rings (3.5" × 5"): Shipping 20 cable management rings in the box at this size means a fully populated 52U rack can be dressed without a separate cable accessories order — and the 1/4-turn mount means repositioning mid-run does not require tools.
- UL2416 + RoHS II: UL2416 listing satisfies the safety certification requirement common in commercial construction specs and data center facility standards; RoHS II compliance supports procurement into EU-regulated environments.
Deployment Considerations:
- The Winter White finish is the right call for open-plan SOC environments, light-colored server rooms, or any facility where a black cabinet conflicts with interior design standards — but confirm the color code (W = Winter White) matches your order before the cabinet ships, since the Black variant carries a different suffix.
- The evidence covers a 52U / 24-inch-wide configuration; if your floor plan constrains aisle depth or your equipment stack is shorter, evaluate the 45U variant in the same CMRX family before committing to this footprint.
The CMRX-52U24-W-1224 is the right fit for a security integrator standing up a centralized NVR and switch rack in a finished interior space — where open-frame access simplifies cable management and the Winter White finish keeps the installation looking deliberate rather than improvised.
