Vertiv CMR-59U12-W-SQM6 59U Open-Frame Rack — Winter White, 12" Depth, M6 Square-Hole

Overview

The Vertiv CMR-59U12-W-SQM6 is a 59U open-frame rack finished in Winter White with a 12-inch depth and 3/8" square M6 hole pattern — the specific configuration to specify when your data center or network room standards require M6 cage-nut mounting and a white finish for visual identification or room aesthetic requirements. The CMR series from Vertiv racks and enclosures ships in multiple height and depth combinations; this SKU locks you into 59U height and 12" depth, so verify your vertical and horizontal footprint requirements before ordering.

Open-frame architecture means unrestricted airflow to front and rear of installed equipment — a meaningful advantage over enclosed cabinets in well-cooled machine rooms where cable accessibility and thermal performance matter more than physical security. The 59U height provides substantial mounting real estate for dense network, AV, or surveillance infrastructure buildouts.

Key Features

• 59U Usable Height: 59U of rack space supports high-density equipment deployments — enough vertical room for a full NVR stack, patch panels, PoE switches, and ancillary network switching gear without splitting across multiple racks.
• 12" Depth: The 12-inch depth is a shallow-rack profile well-suited to wall-mounted or space-constrained telecom rooms, and is compatible with most 1U and 2U network appliances, patch panels, and surveillance recorders that don't require full 24" or 30" depth enclosures.
• M6 Square-Hole (3/8" sq.) Mounting: The CMR-59U12-W-SQM6 uses 3/8" square M6 cage-nut mounting — the industry-standard pattern compatible with virtually all rack-mount equipment shipping today. No thread-matching required; cage nuts are user-installable and interchangeable.
• Winter White Finish: The white color distinguishes this unit from standard black racks in mixed environments or clean-room deployments — useful when rack color coding is part of your physical infrastructure labeling scheme, or when the rack is exposed in a customer-facing space.
• Multi-Configuration Family: The CMR series is also available in 45U and 52U heights and in 6", 10.5", 12", and 16.25" depths. If your project spec changes, sibling SKUs in the same open-frame rack family share the same mounting standard and finish options.
• #12-24 Tapped Mounting Option: In addition to square-hole M6, the CMR series supports #12-24 tapped mounting — useful for legacy equipment that ships with #12-24 screws rather than cage nuts. Confirm which mounting style your equipment requires before installation.

Integration & Compatibility

The M6 square-hole pattern on the CMR-59U12-W-SQM6 is the current EIA-310 standard and is compatible with the overwhelming majority of rack-mount equipment from network, security, AV, and server vendors. If you are deploying network video recorders, managed PoE switches, or patch panels alongside surveillance infrastructure, confirm that your rack-mount hardware ships with M6 cage nuts or includes its own mounting hardware — most enterprise-grade equipment does. The 12" depth accommodates shallow appliances; deep servers or UPS units may require the 16.25" depth variant instead.

Frequently Asked Questions

Q: What is the exact usable height of the CMR-59U12-W-SQM6?

A: The CMR-59U12-W-SQM6 is a 59U rack. The CMR family is also available in 45U and 52U configurations if your installation requires a shorter frame.

Q: What mounting hole standard does the CMR-59U12-W-SQM6 use?

A: It uses 3/8" square M6 (cage-nut) mounting — the current EIA-310 industry standard. The CMR series also supports #12-24 tapped mounting for legacy equipment compatibility.

Q: What depth is this specific SKU?

A: The CMR-59U12-W-SQM6 is the 12-inch depth variant. Vertiv offers the same CMR frame in 6", 10.5", 12", and 16.25" depths — choose based on your deepest rack-mount equipment.

Q: Is the CMR-59U12-W-SQM6 available in black?

A: This specific SKU ships in Winter White. The CMR series is also available in black; you would need to select the corresponding black-finish SKU if black is required.

Q: Is this an open-frame or enclosed rack?

A: Open-frame. There are no side panels or doors, which maximizes airflow and cable access but provides no physical security enclosure. If physical security or dust protection is required, consider an enclosed cabinet variant.

Ted Perry

The CMR-59U12-W-SQM6 is a specific intersection of three independently selectable parameters in the Vertiv CMR line: 59U height, 12-inch depth, and M6 square-hole mounting in Winter White. That 12-inch depth is the spec most likely to trip up an integrator — it is shallow enough for patch panels and managed switches but will not accommodate a full-depth server or a large UPS without a depth extender or a different SKU entirely.

Technical Highlights:

• 59U Height: 59U provides roughly 103.25 inches of rack space — enough vertical capacity to consolidate a full surveillance head-end (NVR, PoE switches, patch panels, KVM) into a single frame without stacking racks.
• M6 Square-Hole Pattern: The 3/8" M6 cage-nut standard is what virtually every enterprise rack-mount device ships expecting. Specifying M6 here means zero adapter hardware and no field-threading headaches.
• 12" Depth: Suits shallow telecom rooms and wall-mount applications where full 24"–30" cabinet depth isn't practical. Verify your deepest appliance before committing — NVRs with hot-swap drive bays often need more than 12".

Deployment Considerations:

• Confirm total equipment depth before ordering this SKU — the 12" depth works for 1U switches and patch panels, but deep storage appliances or UPS units will overhang or not mount at all. The 16.25" depth variant is available in the same CMR family.
• Open-frame racks offer no physical security or dust ingress protection. In a shared or public-access space, pair with a locking enclosure or secure the room perimeter instead of relying on the rack itself.

The CMR-59U12-W-SQM6 is the right specification for a clean-room or customer-visible telecom closet where white finish is required, equipment is predominantly shallow (switches, patch panels, 1U appliances), and full-depth server hardware is absent from the build.
