Vertiv GL24WMCMS-B-SH-00-00 24" 12U Wall-Mount Network Enclosure
Overview
The Vertiv GL24WMCMS-B-SH-00-00 is a 24-inch-deep, 12U wall-mount enclosure finished in black — purpose-built for network closets, telecom rooms, and distributed IT edge deployments where floor space is unavailable or impractical. This specific configuration ships with a swing-handle access control door, giving you quick single-hand access without fumbling for a separate key tool. If you need a larger footprint, the same enclosure family scales to 19U (36") and 25U (48") heights without changing your mounting hardware strategy or access-control workflow. GL24WMCMS-B-SH-00-00 (often searched as GL24WMCMS B SH 00 00) fits installations where the enclosure needs to integrate cleanly with the surrounding infrastructure rather than stand out.
Key Features
- 12U / 24" Height: Twelve rack units of usable space in a 24-inch chassis — enough for a PoE switch, patch panel, and a small UPS without overbuilding for a wiring closet that will never fill past half-capacity. The same enclosure family extends to 19U and 25U if your hardware manifest grows.
- Swing-Handle Access Control: The swing-handle locking mechanism provides secure single-motion access — no separate key management process required during daily maintenance rounds. For environments that need higher assurance, the same product family supports SEAL Combo and SEAL Electronic locking options, so you can upgrade the credential model without replacing the enclosure.
- Black Finish: The black powder-coat finish suits both data center environments and customer-facing spaces where a white enclosure would draw unwanted attention. Winter White is available in the same family for clean-room or medical-adjacent deployments where enclosures are expected to blend with wall surfaces.
- Door Options Across Family (Plexi / Mesh / Solid): This configuration's door type is confirmed swing-handle; the broader product family supports plexi, mesh, and solid door variants. Plexi lets you visually verify LED status at a glance without opening the enclosure — useful in unattended remote sites. Mesh maximizes passive airflow for thermally dense loads. Solid is the cleanest finish for front-of-house or lobby installations.
- Fan Airflow Option: The enclosure supports optional integrated fan airflow — meaningful when you're packing a PoE switch plus a small NVR into a 12U space in a poorly ventilated closet. Passive (None) airflow works fine for lightly loaded or well-conditioned spaces, but if your thermal survey puts the closet ambient above 25°C, specify the fan configuration up front rather than retrofitting.
- Cable Management Flexibility: Available with no cable management, a cable bar, or a full clear cable management panel — the clear option in particular lets you trace cable paths without opening the enclosure, which cuts troubleshooting time in multi-tenant or high-density deployments where misidentified cables are a real operational risk.
Integration & Compatibility
Wall-mount enclosures in the Vertiv GL series are designed to accept standard 19-inch rack-mount equipment — the same gear you'd spec into a floor-standing cabinet. That means 1U/2U managed switches, patch panels, 1U NVRs, and rackmount UPS units all install without adapter rails or custom hardware. The 24-inch depth accommodates most 1U and 2U network appliances with room for proper cable dressing at the rear. For PoE network switches feeding IP camera runs, confirm the switch depth against the 24" interior clear depth to ensure the rear cable egress is not compressed. If your equipment stack includes a rackmount UPS, verify the unit's depth and weight rating against the enclosure's rated capacity before finalizing the configuration. The GL24WMCMS-B-SH-00-00 pairs naturally with Vertiv power and cooling products for a single-vendor edge infrastructure stack. For larger deployments requiring floor-standing capacity, review the full server rack and cabinet category before committing to the wall-mount form factor — wall-mount is the right call only when floor load, space, or physical security requirements drive you to it.
Frequently Asked Questions
Q: What rack unit capacity does the GL24WMCMS-B-SH-00-00 provide?
A: This configuration provides 12U of rack space in a 24-inch-tall enclosure. The same family is also available in 19U (36") and 25U (48") heights if your hardware list exceeds 12U.
Q: What type of door lock does this enclosure use?
A: The GL24WMCMS-B-SH-00-00 ships with a swing-handle access control mechanism. The broader enclosure family also supports SEAL Combo and SEAL Electronic locking options for higher-assurance environments.
Q: Does the GL24WMCMS-B-SH-00-00 include integrated fan cooling?
A: The enclosure family supports both passive (no airflow) and active fan airflow configurations. Confirm which option is included with this specific SKU at the time of order, as thermal requirements vary by installed equipment density.
Q: What cable management options are available?
A: The Vertiv GL series supports no cable management, a cable bar, or a clear cable management panel. The clear panel option is particularly useful in multi-device deployments where tracing cable routes without opening the enclosure saves time.
Q: What equipment depth fits inside this enclosure?
A: The enclosure is 24 inches deep. Verify your equipment's depth against the interior clear depth (accounting for door thickness and rear cable management hardware) before ordering — most 1U and 2U network appliances will fit, but deep UPS units may require measurement.
Q: Is the GL24WMCMS-B-SH-00-00 available in colors other than black?
A: Black is the color for this specific model. Winter White is available as an option within the same GL wall-mount enclosure family for environments where a white finish is preferred.
The GL24WMCMS-B-SH-00-00 earns its place in distributed edge and security infrastructure deployments specifically because of the swing-handle locking configuration — in practice, that single-motion access model cuts the time to get in and out of the enclosure on routine maintenance visits, which matters when you're servicing a dozen wall-mount closets across a campus and every extra minute per closet compounds. The 12U / 24" form factor is the sweet spot for a single-closet IDF serving one floor: a managed PoE switch, a patch panel, and possibly a small rackmount NVR or UPS all fit cleanly without leaving the enclosure 70% empty the way a 25U unit would.
Technical Highlights:
- Swing-Handle Lock: Single-motion access without a separate key tool — operationally faster than keyed cam locks when you're making multiple site visits per week across several closets.
- Fan Airflow Option: The active fan configuration is the right call if ambient closet temps exceed 25°C or if you're installing a thermally dense PoE switch alongside an NVR — passive cooling alone won't protect hardware longevity in a tight, warm space.
- Clear Cable Management Option: The clear cable management panel lets technicians trace and identify cable runs visually before opening the enclosure — a concrete time-saver during moves, adds, and changes in multi-tenant environments where misidentified cables are a persistent issue.
Deployment Considerations:
- Verify your deepest equipment unit against the 24" interior clear depth before ordering — rack-mount UPS units in particular often run 20"+ and leave no room for rear cable dressing in a 24"-deep enclosure.
- The swing-handle mechanism is not rated for high-security key-control environments — if your compliance requirement mandates auditable access logs, specify the SEAL Electronic locking variant from the same family instead.
This enclosure is the right call for single-floor IDF closets in commercial buildings, retail back-of-house network rooms, and distributed edge rack deployments where the equipment inventory is stable and the primary driver is clean installation in a constrained footprint — not maximum rack density.
