Vertiv VR3300-007 42U Open Frame Floor-Standing Server Rack
Overview
The Vertiv VR3300-007 is a 42U open frame rack built for high-density server, networking, and security infrastructure deployments where airflow, accessibility, and load capacity matter more than physical security. At 78.7" H x 23.6" W x 47.2" D and rated for a dynamic load of 2,253 lbs, this rack handles fully populated blade chassis, dense NVR stacks, or mixed IT/security infrastructure without flex or instability under operational conditions. If you're building a head-end room, a network operations center, or a surveillance core in a controlled-access space, the VR3300-007 belongs on your short list — explore the full Vertiv rack and infrastructure catalog for the broader lineup.
Key Features
- 42U Capacity: 42 rack units of usable vertical space means you can stack a full NVR array, PoE switches, patch panels, and UPS in a single footprint — no secondary rack required for most mid-scale deployments. For context, a 42U frame comfortably houses 8–12 2U appliances plus blanking panels and cable management.
- 2,253 lb Dynamic Load Rating: Dynamic load — the weight the rack handles while moving or under operational vibration — is 2,253 lbs. Static capacity goes higher at 2,998 lbs. That's sufficient headroom for the heaviest UPS modules, fully populated server chassis, or dense storage arrays. Don't treat the static number as your working limit; use the dynamic figure when calculating loaded deployments.
- 47.2" Adjustable Depth: The depth is adjustable within the 47.2" envelope, which means you can dial in rail position to match the actual chassis depth of your servers or appliances rather than shimming or over-reaching cable connections. This matters most when mixing 1U switches with 4U storage arrays that have different mounting depths.
- Powder-Coated Steel Construction: The frame is powder-coated steel — not aluminum extrusion. That translates to better rigidity under lateral load and vibration, and it holds up in light-industrial environments where bare aluminum can corrode or deform from incidental contact. The finish also resists scuffs from repeated cable pulls.
- Integrated Casters: Four casters are included, which is the difference between a one-person positioning job and a multi-crew operation. In equipment rooms where floor tiles have to stay undisturbed, casters let you roll the fully-loaded rack into final position rather than lifting it into place. Check your floor tile weight ratings before loading the rack and rolling simultaneously.
- Open Frame Design: No side panels or front/rear doors means convection airflow is unrestricted — critical for high-wattage compute or PoE switching that generates consistent thermal load. Open frame also means faster physical access during installs and troubleshooting. If your site requires physical security at the rack level, plan for a lockable enclosure or cage instead of this model.
- Cable Management: Built-in cable management provisions keep horizontal and vertical runs organized without requiring aftermarket add-ons. In a network switch-heavy deployment, clean cable routing prevents airflow restriction and makes port identification faster during maintenance windows.
- Lockable: Despite the open frame design, the VR3300-007 includes locking capability — useful for controlled-access rooms where individual rack-level access restriction is required by policy, even without full enclosure doors.
Integration and Compatibility
The VR3300-007 is a universal EIA-310 compliant open frame rack. It accepts standard 19-inch rackmount equipment at any U height, making it compatible with NVRs, network video recorders, managed PoE switches, patch panels, KVM switches, UPS systems, and server appliances from any manufacturer. The adjustable depth accommodates shallow 1U networking gear through deep 4U storage systems. For security integrators building surveillance head-ends, this frame pairs naturally with rackmount NVRs and the associated PoE infrastructure feeding camera networks. Plan cable pathways before populating — the open frame gives you flexibility that a closed cabinet doesn't, but that flexibility requires intentional management to stay serviceable long-term.

Frequently Asked Questions
Q: What is the dynamic load rating of the VR3300-007?
A: The VR3300-007 is rated for a dynamic load of 2,253.12 lbs. The static load capacity is higher at 2,998.29 lbs. Use the dynamic figure as your working limit for populated, operational deployments.
Q: Is the VR3300-007 depth adjustable?
A: Yes. The rack supports adjustable depth within its 47.2-inch overall depth envelope, allowing you to position rails to match the actual chassis depth of installed equipment.
Q: Does the VR3300-007 include casters?
A: Yes, casters are included with the VR3300-007, enabling repositioning of the rack during installation without requiring a lift crew. Verify floor load ratings before rolling a fully-loaded rack.
Q: What rack unit capacity does the VR3300-007 provide?
A: The VR3300-007 provides 42U of usable rack space in a floor-standing open frame form factor, with overall dimensions of 78.7" H x 23.6" W x 47.2" D.
Q: Is the VR3300-007 an enclosed cabinet or open frame?
A: The VR3300-007 is an open frame rack — it has no side panels, front door, or rear door. This maximizes airflow and physical access but does not provide the physical security of an enclosed cabinet. It does include locking capability for access restriction within the open frame design.
Q: What material is the VR3300-007 constructed from?
A: The frame is built from powder-coated steel, providing rigidity and durability suitable for commercial and light-industrial equipment room environments.
The spec that stands out most on the VR3300-007 is the 2,253 lb dynamic load rating — that's not a number you'll ever test in a typical security head-end, but it tells you the frame isn't going to rack or twist under the weight of a fully-populated 42U build. I've seen cheaper open frames develop a lean after a few years under dense UPS and NVR loads; this is not that product.
Technical Highlights:
- 2,253 lb Dynamic / 2,998 lb Static: With most 1U appliances running 15–40 lbs each, even a fully populated 42U build lands well under the dynamic ceiling — you have real engineering margin, not a spec that assumes unrealistic packing density.
- 47.2" Adjustable Depth: A 47.2-inch adjustable-depth frame covers the full range from shallow 1U patch panels to deep 4U storage chassis. Adjustable rail position means you're not forcing cable bends to reach fixed mounting points.
- Powder-Coated Steel + Casters: Steel over aluminum for this form factor is the right call in equipment rooms that see regular cart traffic. The included casters make single-person positioning practical — relevant when you're installing in a machine room with raised flooring where you can't drag.
Deployment Considerations:
- Open frame maximizes airflow for high-wattage builds, but it requires the room itself to handle cooling — don't drop this into a closet without validating that ambient CFM can keep up with the thermal load of your populated chassis.
- At approximately 302 lbs unloaded, the VR3300-007 needs two people and a loading dock or freight elevator for delivery intake — plan accordingly for upper-floor equipment rooms without service lift access.
This rack is the right call for a surveillance operations center or server room build where you're mixing NVRs, managed PoE switching, and UPS in a single controlled-access space — specifically where airflow management and equipment density take priority over physical enclosure security.
