Vertiv Cmrx 52U 24 in 30 in Black - CMRX-52U30-B-SQM6

Vertiv CMRX-52U30-B-SQM6 52U Rack Enclosure — Black, M6 Tapped, UL2416-Listed

Overview

The Vertiv CMRX-52U30-B-SQM6 is a 52U rack enclosure finished in black, built around a #12-24 tapped M6 (3/8" square) rail system and listed to UL2416 — the standard governing rack and cabinet structural integrity. If you're deploying network video recorders, managed PoE switches, or edge compute nodes in a surveillance or security head-end room, this cabinet gives you a standardized mounting foundation that accepts the full range of commercial 19-inch EIA-310 rack equipment without adapter hardware.

Vertiv's CMR line is designed for structured cable management and equipment density. The 52U height gives you room to stack a multi-channel NVR, patch panels, PoE switch, and UPS in a single enclosure without compromising cable routing. This fits squarely into the rack enclosures category for integrators building out dedicated security equipment rooms or consolidating distributed head-end gear.

Key Features

• 52U Capacity: Enough vertical space to house a full surveillance head-end stack — NVR, PoE switch, patch panel, UPS, and cable management — without spilling into a second cabinet. Reduces footprint in tight IDF or security closets.
• #12-24 Tapped M6 Rails (3/8" Square): Standard EIA-310 rail pattern means virtually every commercial rack-mount chassis — servers, switches, recorders — drops in without sourcing cage nut conversion kits. The M6 tapped format is the integrator's preference for high-density installs where repeated removal and re-seating wears out cage nuts.
• UL2416 Listing: Verifies the enclosure meets structural load requirements under the UL standard for rack and cabinet assemblies. Relevant when facilities management or AHJ sign-off requires listed equipment — common in government, healthcare, and education deployments.
• RoHS II Compliant: Meets EU hazardous substance restrictions. Required for any project with European export or sustainability reporting obligations.
• Black Finish: Matches standard server room and security operations center aesthetics. The CMRX line also ships in Winter White for environments — broadcast, retail, front-of-house — where the enclosure is visible to end users.

Integration & Compatibility

The M6 tapped rail system is compatible with standard 19-inch rack-mount equipment across Vertiv's infrastructure line and virtually all third-party surveillance, networking, and compute hardware. No cage nuts required — thread directly into the tapped rails with M6 screws. For integrators sourcing a complete head-end solution, pair with a rack-mount UPS and structured cable management accessories to complete the installation.

Frequently Asked Questions

Q: What rail mounting standard does the CMRX-52U30-B-SQM6 use?

A: The enclosure uses #12-24 tapped M6 rails with a 3/8-inch square pattern — standard EIA-310 compatible, accepting M6 screws directly without cage nuts.

Q: Is the CMRX-52U30-B-SQM6 UL-listed?

A: Yes. It carries a UL2416 listing, which covers the structural requirements for rack and cabinet assemblies.

Q: How many rack units does this enclosure provide?

A: The CMRX-52U30-B-SQM6 is the 52U configuration. The CMR line also offers 45U and 59U variants for different capacity requirements.

Q: What cable management hardware is included?

A: The enclosure ships with rack mount hardware and 20 units of 3.5″ × 5″ 1/4-turn D-ring cable managers.

Q: Is this enclosure RoHS compliant?

A: Yes, the CMRX-52U30-B-SQM6 is RoHS II compliant, meeting EU restrictions on hazardous substances.

Ted Perry

The CMRX-52U30-B-SQM6 is the configuration I reach for when building out a dedicated security head-end that needs to grow. The M6 tapped rail — not cage nut — is the detail that matters on a 52U frame: at that density, you're pulling and reseating hardware repeatedly during commissioning, and tapped rails hold torque cleanly without stripping the way field-installed cage nuts can after the third swap.

Technical Highlights:

• UL2416 Structural Listing: Facilities teams and AHJs in government and healthcare projects often require listed enclosures — this clears that gate without a variance request.
• 52U Height: Fits a full surveillance stack (NVR, PoE switch, patch panel, UPS) in one enclosure, keeping the head-end consolidating rather than sprawling across multiple cabinets.
• 20x D-Ring Cable Managers (included): At 3.5″ × 5″, these are sized for structured cabling runs — enough D-rings to dress every rack unit cleanly without a separate accessory order.

Deployment Considerations:

• The 30-inch depth (encoded in the SKU suffix -30-) is the spec to verify against your equipment. Deep 2U/4U NVR chassis with rear-exit cable bundles need the full 30 inches — confirm clearance before specifying a shallower variant.
• The CMR line is available in 45U, 52U, and 59U — if your design is close to 52U capacity, spec the 59U from the start; growing into a second cabinet mid-project is the avoidable mistake.

This enclosure is the right pick for physical security integrators building a clean, AHJ-ready head-end room — particularly on education, healthcare, or government sites where UL2416 and RoHS documentation are part of the project closeout package.
