Vertiv Cmrx 52U 24 in 36 in White - CMRX-52U36-W-SQM6

Vertiv CMRX-52U36-W-SQM6 52U Open-Frame Rack Enclosure

Overview

The Vertiv CMRX-52U36-W-SQM6 is a 52U open-frame rack built for structured IT and security infrastructure deployments where airflow, access, and physical organization matter more than full enclosure. The 36-inch depth accommodates standard 1U and 2U network and security appliances — NVRs, PoE switches, access control servers, and patch panels — without the overhead of a full cabinet footprint. The Winter White finish suits environments where aesthetics are a factor alongside function, such as command centers, finished server rooms, or retail back-of-house installations.

Key Features

• 52U capacity: 52 rack units of usable vertical space means you can consolidate a full mid-size security stack — NVRs, switches, UPS, and patch panels — into a single organized structure rather than managing scattered wall-mount points across a room.
• #12-24 tapped M6 square-hole mounting (3/8″): Industry-standard M6 tapped rails accept the widest range of rack-mount hardware without needing cage nuts. If your equipment uses standard rack ears, it mounts without adapter kits.
• 36-inch depth: Sized to handle full-depth appliances. Most commercial NVRs, UPS units, and managed switches fit without extension brackets or rear-rail adjustments.
• Winter White finish: Available alongside Black in the CMRX family — select White for light-colored server rooms or environments with a facility standards requirement for non-black infrastructure.
• UL2416 listed: Meets UL's standard for information technology equipment racks and cabinets — a specification requirement on many commercial and government installation projects.
• RoHS II compliant: Restricts hazardous substances in electrical and electronic equipment, satisfying procurement requirements in regulated markets and public-sector bids.
• 20x 1/4-turn D-rings (3.5″ × 5″): Included cable management D-rings support organized horizontal cable routing without additional accessory orders. 1/4-turn fastening means field installation is fast — no tools required per ring.

Frequently Asked Questions

Q: What mounting hole standard does the CMRX-52U36-W-SQM6 use?

A: The CMRX-52U36-W-SQM6 uses #12-24 tapped 3/8″ square (M6) mounting holes — the industry-standard rail type that accepts rack-mount equipment without cage nuts.

Q: Is the CMRX-52U36-W-SQM6 UL listed?

A: Yes. The CMRX-52U36-W-SQM6 is UL2416 listed, which is the UL standard for information technology equipment racks and cabinets.

Q: Does the CMRX-52U36-W-SQM6 come with cable management hardware?

A: Yes. The rack ships with 20x 3.5″ × 5″ 1/4-turn D-rings for horizontal cable management — no separate accessory order required for basic cable routing.

Q: What is the depth of the CMRX-52U36-W-SQM6?

A: The rack is 36 inches deep, sufficient for full-depth 1U and 2U appliances including most commercial NVRs, managed PoE switches, and UPS units.

Q: Is the CMRX-52U36-W-SQM6 available in black?

A: The CMRX family is available in both Black and Winter White. The CMRX-52U36-W-SQM6 is the Winter White variant. Check the CMRX family for the black equivalent at the same U-height and depth.

Jerry Tildsen

The CMRX-52U36-W-SQM6 is a straightforward 52U open-frame rack that earns its place in security and IT infrastructure builds where you need M6 tapped rails, 36 inches of usable depth, and UL2416 compliance in a single unit. The Winter White finish is not cosmetic afterthought — it is a deliberate spec for environments with facility color standards or high-visibility command center aesthetics.

Technical Highlights:

• M6 tapped square holes: Eliminates cage nut dependency across the full 52U run — every rail position accepts standard rack ears directly, which matters when you are mounting dozens of 1U devices and do not want to hand-install 100+ cage nuts.
• UL2416 listing: Satisfies the rack-specific UL standard required on many commercial build-outs and public-sector contracts — not just a general electrical listing, but the one written for IT rack structures specifically.
• 20x included D-rings: The 3.5″ × 5″ 1/4-turn D-rings ship in the box, so day-one cable management is handled without a separate accessory purchase. At 20 rings across a 52U frame, you have enough for meaningful horizontal routing throughout the full height.

Deployment Considerations:

• Open-frame means no door, no side panels, and no lock — plan for physical security at the room level rather than relying on the rack itself. This is the correct trade-off for high-density cable environments where airflow and front/rear access matter more than enclosure.
• The 36-inch depth is a fit for most 1U and 2U security appliances, but verify your deepest equipment against this dimension before ordering — some high-density UPS units and large-format NVRs can exceed 30 inches and require additional rear-rail positioning.

Best suited for finished security operations rooms, structured wiring closets, and command center builds where open-frame access, color-matched aesthetics, and a UL2416 compliance checkbox are all required in the same unit.
