Vertiv GL720E-2936-B-1032P 37U Black Plexi Front / Solid Rear Rack Enclosure
Overview
The Vertiv GL720E-2936-B-1032P is a 37U open-frame rack enclosure built for data centers, server rooms, and network equipment installations that demand a structured, standards-compliant home for your hardware. At 29 inches wide and 36 inches deep, this enclosure sits in the mid-depth sweet spot — deep enough to comfortably house most 1U and 2U rack-mount servers, NVRs, switches, and UPS units without the footprint penalty of a full 42U or 600mm-wide cabinet. The GL720E-2936-B-1032P ships in black, pairs a plexi (clear acrylic) front door with a solid PV rear door, and uses standard #10-32 and 3/8-inch square (M6) rail mounting — meaning virtually every rack-mount device you already own will drop straight in.
Part of Vertiv's GL720E enclosure line, this model is available in multiple height, width, and depth configurations. Selecting the 37U / 29-inch / 36-inch variant is the right call when you need to maximize vertical density while keeping the cabinet footprint manageable in a mid-sized equipment room or colocation bay.

Key Features
- 37U Usable Height: 37U gives you meaningful density — enough vertical space for a complete 10Gbps switching stack, a pair of 2U NVRs, a 2U UPS, and patch panels without stacking units on top of each other or splitting your deployment across two cabinets. If you're running a camera system with a dedicated NVR, PoE switch, and storage array, 37U is typically the minimum to stay clean and maintainable.
- 29-Inch Interior Width: The 29-inch width accommodates standard 19-inch rack-mount equipment with adequate clearance on both sides for cable management and airflow. This is wider than EIA-310 minimum — useful if your installation includes bulky cable trays or requires side-panel ventilation clearances per local code.
- 36-Inch Depth: 36 inches of usable depth handles most enterprise-grade servers and storage appliances (many 2U servers run 28–32 inches front-to-rear). It's not a stretch-depth cabinet, so ultra-deep blade chassis may require measurement before you commit — but for standard rack-mount security and networking hardware, 36 inches is comfortable.
- Plexi Front Door / PV Solid Rear Door: The clear acrylic (plexi) front door lets you visually confirm LED status and equipment identity without opening the cabinet — useful in a shared space or any installation where frequent cabinet access is a security or operational concern. The solid PV rear door blocks rear visual access while still providing a defined closure point for cable routing, which matters in environments with strict physical security policies.
- Dual Mounting Rail Standards (#10-32 and 3/8" Sq. / M6): Supporting both imperial (#10-32) and metric (M6 / 3/8-inch square) cage nut formats means you won't be hunting for adapters when mixing American and European equipment in the same cabinet. This is a practical detail that saves time in multi-vendor deployments.
- Black Finish: The black color option is the standard for most data center and equipment room environments — it doesn't show dust accumulation the way white cabinets do, and it matches virtually all rack-mount hardware aesthetics. A Winter White option exists in the GL720E family for environments where white is specified (e.g., certain clean-room or lab deployments).
- Multi-Height and Multi-Depth Family: The GL720E-2936-B-1032P is part of a family spanning 13U, 24U, 31U, 37U, and 44U heights and 32-inch or 36-inch depths. If your load grows, upgrading within the same product line keeps spare parts and installation familiarity consistent. For server rack enclosures, this family breadth is a real operational advantage over single-SKU vendors.
- Mesh Front/Rear Door Option Available in Family: While this specific SKU uses plexi front / solid rear, the GL720E line also ships with mesh front and rear doors for higher-airflow environments. If your thermal load requires maximum convective airflow (high-density compute, tightly packed switches), evaluate the mesh-door variant within the same GL720E family.
Integration & Compatibility
The GL720E-2936-B-1032P follows EIA-310 rack standards, making it compatible with all standard 19-inch rack-mount equipment regardless of manufacturer. The dual mounting rail system (#10-32 and M6) covers the full range of cage nut and clip-nut hardware used across server, networking, AV, and security equipment. This enclosure integrates naturally with Vertiv's own PDU and UPS line — if you're specifying a rack power distribution unit or in-rack UPS alongside this cabinet, the Vertiv ecosystem ensures mechanical fitment and coordinated support. It also accommodates standard cable management accessories (horizontal and vertical lacing bars, cable rings) from any manufacturer that follows EIA-310 dimensions.
For physical security installations, this enclosure is a common housing for NVR stacks, PoE switches, access control panels, and patch panels. The 36-inch depth accommodates most commercial NVR appliances and 1U/2U rack-mount servers without rear cable clearance problems. Pair with a PoE switch to consolidate camera power and data in a single cabinet run. For access control panel installations where the enclosure houses both the network gear and the door controllers, the solid rear door supports cleaner cable egress management than a mesh rear.
If you're planning a full equipment room buildout, review the rack planning and equipment room guide for load capacity, airflow, and power budget considerations before finalizing cabinet count and depth.

The GL720E-2936-B-1032P hits the specification that comes up most often in mid-scale equipment room builds: 37U of vertical space in a 29x36-inch footprint, with a plexi front door so your operations team can visually confirm equipment status without opening the cabinet. That combination of density, modest footprint, and visual accessibility is harder to find than it sounds when you're specifying multiple cabinets across a deployment.
Technical Highlights:
- Dual Rail Standard (#10-32 and M6): Supporting both imperial and metric cage nut formats in a single cabinet eliminates the adapter sourcing problem that comes up constantly in multi-vendor security and networking deployments — servers, switches, NVRs, and PDUs from different manufacturers all mount cleanly.
- Plexi Front / Solid PV Rear Door Pairing: The clear front door provides direct visual access to indicator LEDs and equipment labels without requiring cabinet entry — useful in shared-space installations or anywhere you want to reduce touchpoints. The solid rear door provides a cleaner egress point for structured cable runs than a mesh rear would.
- 37U at 36-Inch Depth: The 36-inch depth accommodates virtually all commercial NVR appliances and 1U/2U rack-mount servers without rear cable pinch. At 37U, you have room for a complete camera-system stack — NVR, redundant PoE switches, patch panels, and a rack-mount UPS — in a single cabinet without compromise.
Deployment Considerations:
- The 29-inch width is wider than the EIA-310 minimum — verify your raised floor tile cut-out or aisle width accommodates this before ordering multiple cabinets for a row deployment. It is not a non-standard dimension, but it's worth confirming against your floor plan.
- This SKU is the plexi front / solid rear configuration. If your installation has high thermal density (blade servers, high-port-density switches), the mesh front/rear variant in the GL720E family will deliver significantly better passive airflow — the solid PV rear on this model restricts convective exhaust.
The GL720E-2936-B-1032P is the right cabinet for a physical security operations room or a mid-size server room where the operations team needs visual equipment confirmation without full cabinet access, thermal loads are moderate, and structured cabling to a solid rear is preferred over open mesh.
