Vertiv CMR-52U10-B-1224 52U Open Frame Rack Cabinet
Overview
The Vertiv CMR-52U10-B-1224 is a 52U open frame rack built for high-density IT infrastructure deployments where maximizing usable rack space matters. At 10.5 inches wide and 24 inches deep, this rack fits into constrained equipment rooms and wiring closets that can't accommodate full-width four-post enclosures — without sacrificing the vertical capacity you need for dense server, network, or power distribution buildouts. The CMR-52U10-B-1224 (often searched as CMR 52U10 B 1224) ships in a black finish and is designed for professional Vertiv infrastructure deployments where accessibility and airflow management take priority over enclosed cabinet security.
Key Features
- 52U of Usable Space: Fifty-two rack units gives you room to stack switches, patch panels, servers, and power distribution units in a single vertical run — avoiding the per-rack overhead of splitting across two shorter units when your equipment list grows past 42U.
- 10.5-Inch Narrow Profile: The reduced 10.5-inch width is the defining spec here. Standard 19-inch rack gear mounts on the internal rails regardless of the external frame width, so you get full equipment compatibility in a footprint that fits side-by-side in narrow closets or against a wall where a 24-inch-wide cabinet simply won't clear the aisle.
- 24-Inch Depth: A 24-inch depth accommodates most 1U and 2U networking gear, patch panels, and power strips without the equipment rear overhanging the frame — relevant when you're working with shallow wall-mount alcoves or drop-ceiling wiring closets where a deeper four-post rack creates clearance issues behind the equipment.
- Open Frame Construction: No doors, no side panels — every U is immediately accessible from front, rear, and sides. For teams running frequent cable pulls, equipment swaps, or ongoing commissioning work, the open frame format cuts labor time compared to reaching into an enclosed cabinet. It also eliminates the airflow restriction that enclosures create when cooling hasn't been engineered for a sealed environment.
- Black Finish: The black color designation on the CMR-52U10-B-1224 is a practical consideration in mixed-vendor equipment rooms where black racks are the established standard, and in visible security or AV installations where finish consistency matters to the end client.
- Vertiv CMR Series Build Quality: The CMR line is Vertiv's commercial open-frame rack family — welded steel construction intended for permanent fixed installations rather than portable or temporary deployments. If you're browsing the broader open frame rack category, this series sits between basic economy frames and Vertiv's heavier-duty two-post relay racks.
Integration and Compatibility
The CMR-52U10-B-1224 accepts standard 19-inch EIA-310 rack-mount equipment on its internal rails. At 10.5 inches of external width, the usable mounting width for equipment follows the EIA standard — verify that your cable management arms or side-mount accessories are compatible with a narrow-frame open rack before ordering. This rack works alongside standard power distribution units, patch panels, and 1U/2U network switches without modification. For deployments requiring side panels, doors, or blanking panels for airflow containment, those are sourced separately — this unit ships as a bare open frame. Integrators planning high-density network switching buildouts should account for horizontal cable management depth when specifying equipment with rear-facing cable runs in a 24-inch-deep frame.
Frequently Asked Questions
Q: What is the external width of the CMR-52U10-B-1224?
A: The external width is 10.5 inches. This is a narrow-profile open frame rack. Standard 19-inch EIA-310 equipment mounts on the internal rails.
Q: What is the depth of the CMR-52U10-B-1224?
A: The rack depth is 24 inches. This accommodates most 1U and 2U networking equipment, patch panels, and power strips without rear overhang.
Q: How many rack units does the CMR-52U10-B-1224 provide?
A: The CMR-52U10-B-1224 provides 52U of vertical mounting space.
Q: Does the CMR-52U10-B-1224 come with side panels or doors?
A: No. This is an open frame rack — no doors, side panels, or blanking panels are included. Those accessories are sourced separately if airflow containment or physical security is required.
Q: What color is the CMR-52U10-B-1224?
A: Black.
Q: Is the CMR-52U10-B-1224 part of the Vertiv CMR series?
A: Yes. It is part of the Vertiv CMR commercial open frame rack line, designed for permanent fixed installations in equipment rooms and wiring closets.
The CMR-52U10-B-1224 fills a specific gap in infrastructure planning: you need 52U of vertical capacity but the room won't give you the 24-inch external width of a standard open frame rack. At 10.5 inches wide, this Vertiv unit fits into wiring closet columns and side-by-side rack rows where a wider frame would block aisle clearance or simply not fit against the wall run.
Technical Highlights:
- 52U Capacity: Fifty-two rack units in a single frame avoids the cost and cable management complexity of chaining two 26U or 30U frames when your equipment list outgrows a standard 42U rack.
- 10.5-Inch External Width: Narrow enough to fit alcoves and chase spaces that reject standard-width frames, while the internal EIA-310 rail spacing remains full 19-inch — no custom mounting hardware required.
- 24-Inch Depth: Deep enough for 1U switches, patch panels, and most 2U appliances without rear overhang, but shallow enough for rooms where a 36-inch or 42-inch deep cabinet would block service access or violate fire egress clearance.
Deployment Considerations:
- Open frame construction means no physical security barrier — if the equipment room is shared or accessible to non-IT personnel, plan for a locking enclosure or cage rather than this unit.
- At 24 inches deep, deeper 2U or 4U servers with rear cable management arms may overhang the back of the frame; measure your deepest equipment before spec'ing this rack into a dense server deployment.
The CMR-52U10-B-1224 is the right call for a narrow wiring closet buildout — think a multi-tenant office floor where the IDF room is a converted storage room and a standard 24-inch-wide rack simply won't clear the door frame or the adjacent electrical panel.
