Vertiv CMR-45U06-B-1224 45U Open-Frame Rack Enclosure, 6-Inch Depth, Black
Overview
The Vertiv CMR-45U06-B-1224 is a 45U open-frame rack in a compact 6-inch depth configuration, finished in black. The CMR series is built for structured cabling, patch management, and lighter network equipment deployments where a fully enclosed cabinet isn't necessary and airflow is a priority over physical security. The shallow 6-inch depth makes this unit practical for wall-hung or tight-corridor installations where a standard 24-inch-deep cabinet simply won't fit — think telecom closets, IDF rooms, and compact head-end spaces.
The #12-24 tapped mounting standard means your standard rack screws thread directly into the rails — no cage nuts required, which speeds up installations and eliminates the fumbling that comes with squeezing cage nuts into tight spaces. For integrators stocking one rail hardware kit across jobs, this is the thread pitch you want.
Open-frame construction allows unrestricted airflow around mounted equipment — passive cooling works in your favor when you're racking patch panels, fiber enclosures, or lightweight managed switches that don't generate significant heat loads. It also simplifies cable routing: there are no side panels to work around, and front/rear access is unrestricted.
Key Features
- 45U Capacity: 45 rack units of usable mounting space — enough for a fully populated patch panel bay, multiple managed switches, and associated cable management hardware without running out of space mid-build.
- 6-Inch Depth: Designed for shallow spaces where standard-depth cabinets can't be used. Patch panels, fiber enclosures, and 1U switches are all comfortably within the depth envelope. Not suitable for deep servers or UPS units.
- Black Finish: Matches standard rack aesthetics in most data rooms and IDF closets. The CMR-45U06-B-1224 (often searched as CMR 45U06 B 1224) ships in black; a Winter White option exists in the CMR family for environments where that finish is preferred.
- #12-24 Tapped Rails: The industry-standard thread pitch for rack mounting screws eliminates the cage nut step, reducing install time per unit. Every integrator's van already carries the right screws.
- Open-Frame Construction: No side panels means unrestricted airflow and cable access from any angle — practical for environments where passive cooling is adequate and physical security of rack contents is handled at the room level.
Compatibility and Integration
The CMR series accepts standard 19-inch EIA rack equipment. The #12-24 thread pitch is compatible with the vast majority of commercial network, AV, and security hardware shipped today. For organizations that have standardized on M6 square-hole or other thread patterns, verify your hardware's rail compatibility before ordering — the CMR-45U06-B-1224 ships with #12-24 tapped rails and does not convert without rail replacement. Review the broader Vertiv rack and enclosure catalog for companion products including cable management arms, blanking panels, and power distribution units that pair with this frame. For deeper equipment, the CMR family includes 10.5-inch, 12-inch, and 16.25-inch depth variants — consider those configurations if you're housing equipment that exceeds the 6-inch depth of this model. This rack is a practical anchor for a structured network infrastructure build in space-constrained environments.
Frequently Asked Questions
Q: What is the rail thread type on the CMR-45U06-B-1224?
A: The CMR-45U06-B-1224 uses #12-24 tapped rails — the standard thread pitch that accepts common rack mounting screws without cage nuts.
Q: What equipment depth can this rack accommodate?
A: The CMR-45U06-B-1224 has a 6-inch rail depth. It is suited for shallow equipment such as patch panels, fiber enclosures, and 1U switches. It is not designed for standard-depth servers, storage arrays, or UPS units.
Q: Is the CMR-45U06-B-1224 available in other depths or colors?
A: The CMR series includes depth options of 6, 10.5, 12, and 16.25 inches, and is available in Black and Winter White. This specific SKU (CMR-45U06-B-1224) is the 45U, 6-inch, black, #12-24 configuration.
Q: Does this rack ship with mounting hardware?
A: Package contents for the CMR-45U06-B-1224 are not detailed in available evidence. Contact the seller prior to ordering if confirmed hardware inclusions are required for your project.
Q: Can the CMR-45U06-B-1224 be wall-mounted?
A: The CMR series is an open-frame rack — wall-mount suitability depends on the wall bracket used and local load-bearing capacity. At 45U, this frame carries a significant equipment load; consult a structural engineer for wall-hung applications and verify that an appropriate Vertiv or compatible wall-mount bracket is specified.
The CMR-45U06-B-1224 is the configuration I'd reach for when a telecom closet or IDF room doesn't have depth to spare but still needs 45U of structured capacity. The 6-inch rail depth is the defining constraint here — it's shallow enough for wall-adjacent installs but rules out anything with a real chassis depth, so plan your equipment list before committing to this frame.
Technical Highlights:
- #12-24 Tapped Rails: No cage nuts needed — this is the thread pitch that ships on most commercial switch and panel hardware, which means faster builds and one fewer hardware bag to carry to the job site.
- 45U Open Frame: 45 rack units of fully open-air mounting space gives you complete front-to-back cable access and passive airflow with no panel obstructions — a real advantage in closets where active cooling isn't part of the design.
- 6-Inch Depth Envelope: Sized for patch panels, fiber enclosures, and 1U managed switches. The CMR series offers four depth options (6, 10.5, 12, 16.25 inches) — if you find yourself needing even a small rackmount firewall, step up to the 10.5-inch variant before you're stuck on-site trying to shim equipment that doesn't fit.
Deployment Considerations:
- Confirm your equipment's actual mounting depth against the 6-inch rail-to-rail clearance before ordering — manufacturer-stated chassis depths sometimes exclude ears and cable connectors, which can add an inch or more.
- At 45U, a fully loaded open-frame rack is heavy and top-heavy; floor-mount or brace it properly. Do not assume a standard wall bracket rated for a smaller frame will handle the load of a fully populated 45U unit.
This frame is well-suited to structured cabling head-ends and IDF closets in mid-size commercial buildings where space is limited, passive cooling is feasible, and the equipment list is patch panels and switching hardware rather than compute or storage.
