Vertiv GL720E-2436-B-1032P 37U 24" x 36" Black Rack Enclosure with Plexi Front Door
Overview
The Vertiv GL720E-2436-B-1032P is a 37U rack enclosure built for data centers, server rooms, and structured cabling deployments where you need a defined footprint without sacrificing airflow options or door flexibility. At 24 inches wide and 36 inches deep, this is the chassis to reach for when your row spacing is tight but your gear is deep — 36 inches of usable depth handles most 2-post-intolerant servers, UPS units, and patch-heavy cable plants without forcing a wider cabinet that disrupts your aisle strategy. The GL720E-2436-B-1032P ships in black and is part of Vertiv's Vertiv rack and enclosure catalog, a line spanning 13U to 44U in both 24" and 29" widths to match almost any floor plan.
Key Features
- 37U of Usable Rail Space: 37U is the practical sweet spot for a mid-density deployment — enough headroom for a full compute stack, a top-of-rack switch, a patch panel tier, and a 2U UPS without stacking to the ceiling. If you routinely run out of U-space before power budget, this is the height to standardize on before stepping up to 44U.
- 24-Inch Cabinet Width: The 24" footprint keeps your row width consistent with standard North American aisle plans (600mm/24" is the dominant floor-tile pitch). If your facility runs 29" cabinets, Vertiv offers a 29" width in the same GL720E family — but the 24" variant is the default for new builds without a specific reason to go wider.
- 36-Inch Depth: A 36" interior accommodates most enterprise servers, storage arrays, and deep UPS chassis that a 32" cabinet would require adapter rails to handle. For gear like APC Smart-UPS or Eaton 9PX that runs 24"–27" chassis depth, you'll have room for rear cable management as well. If your environment is exclusively shallow networking gear, the 32" depth option in the same family saves floor space — but 36" future-proofs the enclosure for the next equipment refresh.
- Plexi Front Door / Solid Rear Door (PV): The plexi front door lets you visually confirm indicator LEDs and drive activity without opening the cabinet — useful in colocation or managed service environments where walk-the-row status checks are part of the routine. The solid PV rear door provides a physical barrier against accidental rear-access contact with live cabling and patch fields, which matters in shared or multi-tenant rooms. If your cooling strategy relies on a hot-aisle/cold-aisle containment system with perforated doors, Vertiv also offers a mesh front/rear door configuration in this same enclosure line.
- #10-32 and 3/8" Square (M6) Mounting Rails: Supporting all three major mounting standards — #10-32 (common on US networking gear), 3/8" square cage-nut (common on servers and storage), and M6 metric (required by most European and newer enterprise hardware) — means this enclosure works without adapter kits across a mixed-vendor environment. If you're standardizing a multi-brand stack, this flexibility eliminates the nuisance of per-device hardware sourcing.
- Black Finish: Black is the standard finish for data center and server room deployments where aesthetics and brand consistency matter. If your facility specifies Winter White for lab or office environments, the GL720E line supports that colorway in the same configurations.
- Multi-Height Family (13U–44U): The GL720E is available in 13U, 24U, 31U, 37U, and 44U heights, so you can match rack height precisely to row density and cooling zone requirements without mixing enclosure brands. Standardizing on one family simplifies procurement, spare parts, and door interchangeability across a multi-rack deployment.
Integration and Compatibility
The GL720E-2436-B-1032P is designed to integrate into standard server rack and enclosure deployments alongside Vertiv's PDU, KVM, and cable management accessories. The triple rail-standard (M6/#10-32/3/8" sq.) ensures compatibility with the broadest range of rackmount gear. For environments requiring structured cabling within the enclosure, pair this cabinet with horizontal and vertical cable management panels sized for 24" wide cabinets. If your deployment includes high-density power distribution, Vertiv's own PDU portfolio mounts natively in the rear vertical rail space. Before finalizing, verify that your deepest chassis — measured from the front mounting rail to the rear connector — fits within the 36" interior depth with room for power and data cabling at the rear.
For facilities planning a full rack row, review the rack planning and enclosure selection options to match consistent depth and height across the aisle. If you're deploying in a space with floor-tile constraints, confirm that the 24" exterior width (plus side-panel clearance) aligns with your tile grid before ordering.
Frequently Asked Questions
Q: What door configuration does the GL720E-2436-B-1032P ship with?
A: This specific configuration includes a plexi (clear acrylic) front door and a solid rear door (PV designation). If you need mesh perforated doors for airflow-optimized deployments, that configuration is available separately in the GL720E family.
Q: What mounting standards does the GL720E-2436-B-1032P support?
A: The enclosure supports #10-32, 3/8" square (cage nut), and M6 metric rail standards — covering the full range of US and international rackmount hardware without adapter kits.
Q: Is the GL720E-2436-B-1032P available in other sizes or colors?
A: Yes. The GL720E family spans 13U, 24U, 31U, 37U, and 44U heights, in 24" and 29" widths, and in both Black and Winter White finishes. The 36" depth is also available alongside a 32" depth variant in the same family.
Q: What is the interior usable depth of the GL720E-2436-B-1032P?
A: The cabinet's nominal depth is 36 inches. Actual usable depth between front and rear mounting rails will be less — measure your deepest chassis and confirm against Vertiv's published interior rail-to-rail dimension before installing deep servers or UPS units.
Q: Can the GL720E-2436-B-1032P be used with Vertiv PDUs and cable management accessories?
A: The GL720E enclosure line is designed to accept Vertiv's vertical and horizontal PDUs and cable management accessories sized for 24"-wide cabinets. Verify accessory part numbers against Vertiv's compatibility matrix for this enclosure family before ordering.
Q: What is the difference between the plexi door and the mesh door option in this family?
A: The plexi door provides visibility into the cabinet without opening it — useful for LED status checks in colocation or managed rooms — but offers less passive airflow than perforated mesh. If your cooling design depends on front-to-rear convective or forced airflow, the mesh door configuration will deliver better thermal performance. Choose plexi when visual access is the priority; choose mesh when airflow is the constraint.
The GL720E-2436-B-1032P sits in the middle of Vertiv's GL720E height range at 37U — and the 24" x 36" footprint with a plexi front/solid rear door combination is a configuration I see specified most often in colocation suites and enterprise server rooms where operators want visual cabinet status without opening doors in a live aisle. The triple rail standard (#10-32, 3/8" square, M6) is what seals the deal for mixed-vendor environments where you might be racking Cisco, Dell, and APC gear side by side.
Technical Highlights:
- 36" Depth: Accommodates deep chassis (24"–28" server depth plus rear cabling clearance) that a standard 32" cabinet forces you to manage with extension rails — 36" handles it natively and leaves room for rear vertical cable management.
- Triple Mounting Standard (#10-32 / 3/8" sq. / M6): No cage-nut conversion kits required across a mixed US/EU hardware stack — all three standards are supported at the rail, which matters on a 37U cabinet where you may be sourcing rack hardware from multiple vendors across the full height.
- Plexi Front / Solid PV Rear: Plexi front enables walk-the-row LED inspection without breaking cabinet seal; solid rear closes off the cable and power zone from accidental contact — a meaningful distinction in multi-tenant or shared infrastructure rooms versus single-operator environments where a mesh rear would be preferred for passive cooling.
Deployment Considerations:
- The 36" nominal depth is the exterior or frame dimension — confirm Vertiv's published front-to-rear rail-to-rail measurement before committing deep-chassis UPS or storage arrays, particularly units exceeding 26" chassis depth.
- This configuration ships with a solid (not perforated) rear door. If your cooling design relies on rear door heat exchangers or rear-to-aisle airflow, this door will need to be swapped or the mesh-door GL720E variant specified instead — the plexi/solid door combination is designed for environments with precision cooling, not open-aisle convective setups.
The GL720E-2436-B-1032P is the right specification for a managed colocation cage, a mid-density enterprise server room with precision cooling, or a structured cabling head-end where 37U of organized, visually accessible rack space in a 24"-wide footprint is the design requirement.
