Vertiv GL24WMS-B-00 12U Wall Mount Cabinet Enclosure

The Vertiv GL24WMS-B-00 is a 12U wall mount cabinet enclosure designed for space-constrained IT and security deployments where floor space is unavailable and rack-density demands are modest. Part of Vertiv's GL-series wall mount family, the GL24WMS-B-00 ships in solid black — a practical finish for data closets, back-of-house telecom rooms, and distributed security equipment nodes where aesthetics matter less than organization and access control.

Wall mount enclosures in this family are available in multiple height configurations — 24" (12U), 36" (19U), and 48" (25U) — and two depth options: 18" and 24". The GL24WMS-B-00 designator reflects the 24" width, wall mount format, and solid black finish. If your switch stack, patch panel, or NVR requires more clearance front-to-back, the 24" depth variant provides additional room for cabling and card-edge gear without requiring a full floor-standing frame.

Key Features

• Solid Door Configuration: The solid door on this variant blocks visual access to internal equipment — useful in customer-facing spaces, lobbies, or anywhere you want rack contents out of sight without a separate cabinet. If airflow is a concern in high-load installs, the mesh door variant in the same family trades visual concealment for passive ventilation.
• Multiple Height Options: The GL-series spans 12U, 19U, and 25U in the same wall mount footprint, so you can right-size the enclosure to your actual equipment count rather than over-provisioning a floor cabinet for a handful of 1U devices.
• Depth Flexibility: Choosing between 18" and 24" depth lets you match the enclosure to your deepest piece of equipment — typically a PoE switch or NVR. Undersizing depth is a common install mistake that forces awkward cable routing or prevents the door from closing.
• Airflow Options: The GL-series offers none, fan-assisted, and clear-panel airflow configurations. For passive installs with light PoE switch loads, no-fan is quieter and eliminates a maintenance item. Fan-assisted variants are the right pick when ambient temperatures in the closet regularly exceed equipment ratings.
• Black Finish: The -B-00 suffix confirms the solid black finish — consistent with standard data closet and security system aesthetics. A lighter finish variant exists in the same family if your facility standards require it.
• Wall Mount Format: Keeping equipment off the floor reduces vulnerability to flooding, cleaning equipment contact, and accidental impact — relevant in warehouse and light industrial environments where network switches and security gear share space with operational equipment.

Integration and Compatibility

The GL24WMS-B-00 follows standard 19" EIA rack unit spacing, making it compatible with virtually any 1U–4U rack-mountable equipment: network video recorders, PoE switches, patch panels, UPS units, and access control hardware. When planning your loadout, verify the combined depth of your deepest device plus cable bend radius fits within the selected depth (18" or 24"). For heavier equipment concentrations — multiple NVRs, dense patch fields, or UPS modules — confirm wall stud spacing and load rating before mounting. The wall mount bracket pattern on this series is designed for standard stud or concrete anchor installations.

If you are deploying a Vertiv power or cooling stack alongside this enclosure, the GL-series integrates cleanly with Vertiv's GXT UPS line and PDU accessories without adapter kits. For wall mount cabinet sizing guidance across brands and configurations, verify your tallest equipment's U-height before committing to the 12U form factor of this unit.

Frequently Asked Questions

Q: What specific height and depth does the GL24WMS-B-00 correspond to within the GL-series family?

A: Based on the MPN structure, the GL24WMS-B-00 is the 12U (24") wall mount variant in solid black. The GL-series also includes 19U (36") and 25U (48") heights, as well as 18" and 24" depth options across the family. Confirm the exact configuration with the product datasheet before ordering if your application requires a specific depth.

Q: Can I add fans to the GL24WMS-B-00 after installation?

A: The GL-series offers factory-configured airflow options including no-fan, fan-assisted, and clear-panel variants. Whether fans can be field-added to the solid/no-fan variant depends on the chassis design. If active cooling is a known requirement, specify the fan-configured variant at time of order rather than planning a retrofit.

Q: Is the GL24WMS-B-00 compatible with standard 19" rack equipment?

A: Yes. The GL-series uses standard EIA 19" rack unit spacing, so it accepts any standard 1U, 2U, or deeper rack-mount equipment up to the enclosure's internal depth. Verify that your deepest device fits within the 18" or 24" depth option you select.

Q: What door style does the GL24WMS-B-00 ship with?

A: The GL24WMS-B-00 ships with a solid door in black. The GL-series family also offers plexi (clear acrylic) and mesh door configurations if you need visual access or improved passive ventilation without changing the cabinet footprint.

Q: Is this enclosure suitable for security system equipment like NVRs and PoE switches?

A: Yes. Wall mount enclosures in this class are commonly used to house NVRs, PoE switches, patch panels, and access control hardware in security deployments. Verify that your NVR's depth and the combined cable management clearance fit within the chosen depth variant before finalizing the order.

The GL24WMS-B-00 is the solid-door, black-finish variant of Vertiv's GL-series wall mount cabinet — a 12U enclosure that hits the sweet spot for distributed security nodes where you need organized, locked rack space without committing floor real estate to a full 42U frame. I specify this series regularly for IDF closets and security equipment rooms where the equipment list is short but the installation needs to look clean and stay organized for the life of the system.

Technical Highlights:

• Solid Door: Blocks visual access to internal equipment and provides a basic physical deterrent — the right call for lobbies, break rooms, or any space where rack contents shouldn't be visible to non-technical staff.
• Family Depth Options (18" and 24"): The 24" depth variant accommodates most 1U NVRs and managed PoE switches with room for proper cable dressing behind the equipment — the detail that separates a clean install from a rat's nest in 18 months.
• Multiple Height Configurations (12U / 19U / 25U): Right-sizing the cabinet to your actual U-count prevents the common mistake of over-specifying a 42U floor cabinet for four devices, and keeps the wall load manageable for standard stud framing.

Deployment Considerations:

• For security deployments with a PoE switch, NVR, and patch panel, verify combined weight against your wall substrate before mounting — drywall anchors alone are not sufficient for a loaded 12U cabinet; lag into studs or use a backing plate.
• The solid door configuration limits passive airflow — if your PoE switch and NVR run warm in an enclosed space, budget for the fan-variant or plan supplemental ventilation; thermal throttling in a locked cabinet is a common field callback.

The GL24WMS-B-00 is the right enclosure for a compact security equipment node: a closet or back-of-house space housing a single NVR, a PoE switch, and a patch panel where the solid door keeps contents out of sight and the 12U height avoids over-building for a modest equipment list.
