Vertiv GL720E-2432-B-1032MS 37U 24”x32” Black Mesh Rack Enclosure
Overview
The Vertiv GL720E-2432-B-1032MS is a 37U open-frame-compatible enclosed rack built for data centers, server rooms, and security equipment deployments where airflow management and structural rigidity both matter. At 24 inches wide and 32 inches deep, it fits standard 19-inch rackmount gear while leaving enough front-to-rear depth for cable management, patch panels, and 1U/2U switches without crowding. The mesh front and mesh rear door configuration is the defining specification here — choose this model when you need passive airflow through the enclosure rather than a solid or plexi door that traps heat behind glass.
This enclosure belongs to the Vertiv rack and enclosure line, a product family commonly specified for telecom, enterprise IT, and physical security head-end rooms. If you are deploying NVRs, video management servers, PoE switches, or access control hardware in a dedicated equipment room, this rack is sized for mid-scale builds — large enough to house a full security head-end, compact enough to fit in a wiring closet or IDF.
Key Features
- 37U Usable Height: 37U gives you room for a full NVR stack, patch panels, a PoE switch layer, and a UPS shelf in a single enclosure — enough vertical space to avoid splitting a security head-end across two racks. The GL720E family also ships in 44U, 31U, 24U, and 13U configurations, so if your equipment list grows or shrinks, you stay within the same hardware family for spares and accessories.
- 24-Inch Width: Standard 24” rack width accommodates all standard 19” EIA-310 rackmount equipment. The 5” of rail-to-panel space on each side handles blanking panels, vertical cable managers, and side-mounted PDU rails without interference.
- 32-Inch Depth: A 32” front-to-rear interior dimension is the right call for 1U and 2U servers or deep switching gear. It’s not excessive for shallow patch panels, but verify that any equipment exceeding 28” of chassis depth (cables included) will still clear the door swing before ordering. The GL720E family also ships in 36” depth if you are housing blade servers or full-depth storage arrays.
- Mesh Front and Mesh Rear Doors: Both front and rear doors are perforated mesh on this configuration. That means natural convective airflow moves through the cabinet without forced supplemental fans in low-density deployments. In higher-density builds, mesh doors let you add top-mounted or side-mounted fan trays without fighting a solid door’s thermal resistance. If your equipment room relies on row-cooling or in-row CRAC units, mesh containment works cleanly with hot-aisle/cold-aisle arrangements.
- Black Finish: The GL720E-2432-B-1032MS ships in black — the standard finish for modern equipment rooms and security operations centers. Vertiv also offers Winter White in the same family for environments where lighter color is specified (clean rooms, certain healthcare facilities).
- #10-32 and 3/8” Square (M6) Mounting Rails: The mounting rail system supports #10-32 threaded, 3/8” square (cage nut), and M6 metric hardware. That covers virtually every rackmount device you’ll encounter — legacy #10-32 PDUs and older Cisco gear, standard square-hole equipment, and metric-spec servers from HPE and Lenovo. You will not need adapter rails or conversion kits for mixed fleets, which matters in security head-ends that combine IT and purpose-built physical security appliances.
- Multi-Configuration Family: Beyond the height and depth variants already noted, the GL720 family supports plexi front / solid rear and plexi front / vented rear door combinations, giving you a migration path if a future equipment addition changes your airflow requirements. Accessories, PDU mounting positions, and blanking panels are shared across the family.
Integration and Compatibility
The GL720E-2432-B-1032MS integrates with the broader Vertiv infrastructure ecosystem. Vertiv’s Geist-series rackmount PDUs are designed to mount in GL720 enclosures without adapter brackets, and Vertiv’s UPS platforms (GXT and Liebert lines) are available in 19” rack form factors that fit the 37U interior directly. If you are specifying a complete security infrastructure rack, pairing this enclosure with a managed PoE switch and a rackmount NVR gives you a self-contained head-end that can be pre-staged and shipped as a complete assembly.
The #10-32 / M6 rail compatibility means this enclosure works with physical security appliances from Hanwha, Axis, Milestone appliances, Genetec hardware, and standard IT brands without modification. For integrators running structured cabling into the rack, the 32” depth leaves adequate space behind equipment for patch panel and cable management installations that keep the enclosure serviceable long-term.
Review your equipment’s maximum chassis depth against the 32” interior before finalizing. In a 24”-wide enclosure, vertical cable managers inside the rack reduce usable rail width slightly — plan cable management before populating rails if you are running a dense wiring scheme.
Frequently Asked Questions
Q: What is the usable rack height of the GL720E-2432-B-1032MS?
A: The GL720E-2432-B-1032MS provides 37U of usable rack space. The GL720E family is also available in 44U, 31U, 24U, and 13U configurations if your deployment requires a different height.
Q: What door configuration does the GL720E-2432-B-1032MS ship with?
A: This specific model ships with mesh front and mesh rear doors, which support passive airflow through the enclosure. Vertiv offers alternative door configurations (plexi front/solid rear and plexi front/vented rear) in the GL720E family if your environment requires different thermal management.
Q: What mounting hardware does the GL720E-2432-B-1032MS support?
A: The mounting rails support #10-32 threaded fasteners, 3/8-inch square (cage nut), and M6 metric hardware — covering legacy, standard, and metric-spec rackmount equipment without adapter kits.
Q: What are the interior dimensions of the GL720E-2432-B-1032MS?
A: The enclosure is 24 inches wide and 32 inches deep. A 36-inch depth variant is available in the GL720E family for installations requiring more front-to-rear clearance for deep servers or dense cabling.
Q: Is the GL720E-2432-B-1032MS available in colors other than black?
A: The GL720E family is available in black (this model) and Winter White. Winter White is typically specified for healthcare or clean-room environments where lighter finishes are required.
Q: Can the GL720E-2432-B-1032MS be used for physical security head-end deployments?
A: Yes. The 37U height, #10-32/M6 rail compatibility, and mesh door airflow configuration make it a practical choice for security head-end rooms housing NVRs, PoE switches, access control servers, and rackmount UPS units. Verify that individual equipment chassis depths do not exceed the 32-inch interior depth before specifying.
When I spec a security head-end rack, the door configuration is the first decision point — and the GL720E-2432-B-1032MS gets it right for most equipment room deployments. The dual mesh door setup (front and rear) keeps passive airflow viable even in moderate-density builds, which matters when you are housing PoE switches, NVR appliances, and a rackmount UPS in the same 37U enclosure. I have seen solid-door racks turn a well-designed head-end into a thermal problem inside 18 months as equipment gets added — mesh avoids that entirely.
Technical Highlights:
- 37U Vertical Capacity: Enough rack space for a full security stack — NVR, managed PoE switch, patch panel, UPS, and spare room for expansion — without the floor footprint of a 42U or 44U enclosure.
- 24”x32” Interior: The 32” depth handles the majority of 1U and 2U security appliances comfortably; the 24” width is EIA-standard, so no adapter rails are needed for any 19” equipment.
- Triple Rail Compatibility (#10-32 / 3/8” sq. / M6): Mixed fleets — Cisco switches on #10-32, HPE servers on M6, Vertiv PDUs on cage nut — all mount without conversion hardware. This is the spec that saves labor on day one of a complex head-end build.
Deployment Considerations:
- Verify your deepest piece of equipment plus its cabling radius fits within 32 inches before signing off on the rack selection. If any device exceeds that with cables dressed, step up to the 36” depth variant in the GL720E family.
- The mesh door configuration is optimized for open-air or hot-aisle/cold-aisle room environments. In a small wiring closet with no active cooling, dense GPU or high-wattage compute gear will still need supplemental fan trays even with mesh doors — passive airflow alone is not a substitute for active cooling above moderate power densities.
The GL720E-2432-B-1032MS is the right call for a security operations center or dedicated IDF room deploying a mid-scale physical security stack — typically 20 to 60 cameras with centralized NVR, switching, and power — where managed airflow and mixed-vendor rail compatibility are both required on day one.
