Vertiv VR3305 45U Floor-Standing 19-Inch Server Rack Enclosure
Overview
The Vertiv VR3305 is a 45U floor-standing server rack enclosure built for data centers, server rooms, network closets, and equipment-dense deployments where you need a full-height, standardized 19-inch cabinet with a compact floor footprint. At 600mm wide by 1162.5mm deep, the VR3305 lands in the middle of the rack market — deep enough to accommodate most 1U through 4U servers and patch panels without the footprint of a 800mm-wide cabinet. If you're fitting multiple racks into a raised-floor environment or hot-aisle/cold-aisle layout, this profile matters. The steel construction keeps it rigid under load, and the black finish is standard for data center deployments. Sourced factory-new from channel-direct distribution — no grey-market, no parallel imports.

Key Features
- 45U Usable Height: 45 rack units gives you room to populate a full-height cabinet without creative stacking. In a typical 1U server environment that's 45 devices per rack — relevant when you're calculating rack density against floor space in a constrained server room.
- 600mm Wide Footprint: The 600mm (approximately 24-inch) width is the standard data center rack width, keeping the VR3305 compatible with raised-floor tile layouts and hot/cold aisle row spacing designed around the 600mm module. Wider 800mm options exist for high-density cable runs, but most mid-range deployments don't need them.
- 1162.5mm Usable Depth: At roughly 1162mm interior depth, the VR3305 accommodates standard 1U through 4U servers, storage arrays, and UPS units that run up to about 1000mm in mounted depth — enough clearance for cable management behind the equipment without jamming hardware against the rear door.
- 19-Inch EIA Standard Rail Spacing: The 19-inch rail standard means every server, switch, patch panel, and KVM you stock will mount without adapter brackets. The included M6 cage nut and screw kit (50 pieces) lets you start racking equipment immediately after leveling and positioning the cabinet — no separate hardware order required.
- Steel Construction: A steel enclosure doesn't flex under mixed equipment loads the way lighter-gauge alternatives can. For a fully populated 45U cabinet with servers, storage, and UPS gear, structural rigidity translates to stable door alignment, reliable grounding paths, and predictable equipment positioning over time.
- Floor-Standing Form Factor: Floor-standing deployment keeps the center of gravity low and avoids the weight rating constraints of wall-mount or two-post open-frame racks. For heavy storage arrays or UPS units positioned at the bottom of the cabinet, a floor-standing enclosure is the right choice over any overhead or wall-mounted alternative.
- Black Finish: Standard data center black. Matches most co-location environments, reduces light reflection in low-lit server rooms, and avoids the dated appearance of grey cabinets in modern facilities.
Integration & Compatibility
The VR3305 pairs with standard network infrastructure components — 19-inch patch panels, 1U and 2U switches, PDUs, cable management arms, and blanking panels all mount to M6 threaded rails without modification. For power distribution within the rack, pair it with a vertical or horizontal PDU sized to your circuit load. If you're managing airflow thermally, blanking panels for unused rack units are essential — a fully open 45U rack without blanking creates bypass airflow that undermines any in-row or overhead cooling strategy. If you're planning a larger installation, review our rack and enclosure selection guide for guidance on depth, width, and load capacity decisions before committing to a rack line. Also consider pairing with rack-mount PDUs to manage circuit distribution inside the VR3305 cleanly.

Frequently Asked Questions
Q: What is the interior usable depth of the VR3305?
A: The VR3305 has an overall depth of 1162.5mm. Interior usable depth for mounted equipment will be somewhat less once door clearance and cable management space are accounted for — plan for equipment up to approximately 1000mm in depth for comfortable rear cable access.
Q: Does the VR3305 include mounting hardware?
A: Yes. The package includes 50x M6 cage nuts and screws, enough to get a substantial portion of the rack populated on arrival without ordering additional hardware.
Q: What is the weight of the VR3305?
A: The VR3305 weighs approximately 340 lbs. Plan your installation route and team size accordingly — a fully populated 45U cabinet will be substantially heavier, and floor load ratings should be verified before placement in any raised-floor environment.
Q: Is the VR3305 compatible with standard 19-inch rack equipment?
A: Yes. The VR3305 uses EIA standard 19-inch rail spacing, making it compatible with the full range of 1U through 4U servers, switches, patch panels, UPS units, KVM drawers, and other standard rack-mount hardware.
Q: What rack width does the VR3305 use?
A: The VR3305 is 24 inches (approximately 600mm) wide, which is the standard data center cabinet width. This fits standard hot/cold aisle layouts and raised-floor tile grids designed around the 600mm module.
Q: Can the VR3305 be used in a co-location facility?
A: The VR3305 is a floor-standing, 19-inch standard rack enclosure in the industry-standard 600mm width — it is dimensionally compatible with typical co-location cage and row layouts. Confirm specific facility requirements (locking doors, grounding lugs, cable entry points) with your co-location provider before deployment.
The VR3305 is a 45U, 600x1162.5mm steel floor-standing enclosure — and those dimensions are the core of the buying decision. At 340 lbs empty, this is a serious piece of infrastructure. Before you specify the VR3305, know your floor load rating and your installation path from the loading dock to the rack row. A fully populated 45U cabinet with servers and UPS gear will push well past 1,000 lbs total.
Technical Highlights:
- 45U Capacity: Full-height 45U gives you the maximum usable space in a floor-standing cabinet format — relevant for consolidating equipment from multiple smaller racks or building out a dense compute row from scratch.
- 600mm Width Standard: The 600mm (24-inch) footprint matches the dominant data center aisle grid standard, keeping row alignment clean and simplifying raised-floor tile planning in any facility built to EIA or TIA-942 row layouts.
- 1162.5mm Depth: Deep enough for modern 2U servers and storage arrays that routinely hit 900–1000mm in chassis depth, with margin for rear cable management — a detail that matters on day 90 when you're re-cabling, not just day 1 when you're racking.
Deployment Considerations:
- At 340 lbs empty, the VR3305 requires at minimum a two-person lift team and ideally a pallet jack or server room cart rated for the load. Plan the delivery route before the equipment arrives.
- The 50-piece M6 cage nut kit covers a portion of 45U — if you're fully populating the rack on day one, order additional cage nut sets in advance. Running out of cage nuts mid-build is a common and avoidable delay.
The VR3305 is the right specification for a mid-density server room build-out or co-location deployment where 600mm-wide rows are the facility standard and you need a full 45U of vertical space per cabinet. It is not the right pick for high-density GPU or blade deployments that require 800mm width for airflow ducting and high-density cable trays — in those cases, move to the wider Vertiv VR series variants.
