Vertiv CMR 59U 24 in 12 in Black - CMR-59U12-B-1224

Vertiv CMR-59U12-B-1224 59U Open-Frame Rack, 12-Inch Depth, Black

Overview

The Vertiv CMR-59U12-B-1224 is a 59U open-frame rack designed for structured equipment installations where cable accessibility, airflow, and flexible mounting matter more than enclosure security. With a 12-inch rail depth and black finish, it fits neatly into network infrastructure and physical security deployments where open-frame is the correct architecture — think IDF closets, camera head-end rooms, and network operations racks where technicians need front-and-rear access without unlatching doors. The CMR-59U12-B-1224 (often searched as CMR 59U12 B 1224) is part of Vertiv's Vertiv rack and enclosure line, which spans multiple height and depth configurations for different density requirements.

Key Features

• 59U Height Capacity: 59U of usable rack space accommodates high-density equipment stacks — enough headroom to combine patch panels, switches, NVRs, and UPS hardware in a single frame without running short mid-deployment. The CMR family also spans 45U and 52U configurations if your headcount is lower.
• 12-Inch Rail Depth: The 12-inch depth option targets shallow-mount equipment — thin patch panels, PDUs, and access control hardware — where a full 24-inch cabinet wastes footprint. If you are mounting deeper NVRs or UPS units, verify equipment depth against this spec before ordering; the CMR line offers 6-inch, 10.5-inch, and 16.25-inch depths as well.
• Multiple Mounting Configurations: Rails support #12-24 tapped, 3/8-inch square (M6), and smooth/clear hole patterns, covering the three dominant rack unit standards in active use. That flexibility means you are not hunting for cage nuts or adapters to mix vendor equipment on the same frame.
• Black Finish: The black powder coat blends into most NVR and server room environments and resists cosmetic wear in high-access installations. Winter White is available in alternate SKUs if your facility standard requires it.

Integration & Compatibility

The CMR-59U12-B-1224 supports standard EIA-310 rack equipment. The three hole-pattern options (#12-24, M6, and clear) mean it accepts the majority of rackmount panels, switches, and recorders without specialty hardware. Verify that your heaviest equipment does not exceed the frame's rated load capacity — consult the power distribution and equipment specs for your specific load before finalizing the rack layout.

Frequently Asked Questions

Q: What is the rail depth of the CMR-59U12-B-1224?

A: The CMR-59U12-B-1224 is configured with a 12-inch rail depth. The CMR family also offers 6-inch, 10.5-inch, and 16.25-inch depth options in separate SKUs.

Q: What mounting hole patterns does the CMR-59U12-B-1224 support?

A: It supports three patterns: #12-24 tapped, 3/8-inch square (M6), and clear (smooth) holes — covering the primary EIA rack standards used across most commercial equipment.

Q: What height configurations are available in the CMR series?

A: The CMR line includes 45U, 52U, and 59U heights. The CMR-59U12-B-1224 is the 59U variant with a 12-inch depth in black.

Q: Is the CMR-59U12-B-1224 available in colors other than black?

A: Yes. The CMR series is available in Winter White as an alternate finish; the black variant is the CMR-59U12-B-1224.

Jerry Tildsen

The CMR-59U12-B-1224 is the open-frame answer to a specific question I hear often in camera head-end and IDF buildouts: how do you rack a lot of shallow equipment — patch panels, PoE switches, access control hardware — without eating floor space with a full 24-inch enclosed cabinet? At 59U with a 12-inch rail depth and three hole-pattern options, this frame handles mixed vendor gear without the cage-nut scramble that shallow-depth proprietary racks often force on you.

Technical Highlights:

• Three Hole Patterns (#12-24, M6, Clear): Most integrators carry gear from multiple vendors with different rail standards. Having all three patterns on one frame eliminates adapter kits and speeds installation when you are mixing Vertiv PDUs, third-party switches, and OEM NVRs on the same frame.
• 59U vs. 45U/52U Headroom: The extra U count matters in dense surveillance head-ends where you are stacking NVR storage, PoE switch tiers, UPS, and patch panels. Running out of U-space mid-project and having to add a second rack is a real cost; the 59U option prevents that in all but the largest deployments.
• 12-Inch Depth: Correctly sized for shallow-mount hardware. Pairing this with deep UPS or server units is a mismatch — verify equipment depth before committing to this SKU over the 16.25-inch variant.

Deployment Considerations:

• Open-frame means no environmental protection — if the installation space has dust ingress, airborne particulates, or public access, a closed cabinet is the correct choice.
• The 12-inch depth is a hard physical constraint; any rackmount equipment deeper than roughly 10–11 inches will not seat properly on these rails without extension brackets.

The CMR-59U12-B-1224 is the right call for a controlled-access security equipment room or wiring closet where technicians need fast, unobstructed reach to every U-space — not for open-floor or public-area installs where enclosure matters.
