Vertiv VRA6055 Pass-Through Side Panels 42U x 1200mm
Overview
The Vertiv VRA6055 pass-through side panels are purpose-built enclosure accessories for the Vertiv VR open-frame rack series, specifically engineered for 42U frames with a 1200mm depth footprint. If you are running a VR3300 or VR3350 rack and need to close the sides without blocking airflow or cable routing, these panels address that requirement directly — the pass-through design allows cables and airflow paths to remain unobstructed while still providing physical separation or containment between adjacent racks or aisle segments. Unlike solid blanking panels, the pass-through construction makes the VRA6055 a practical choice in hot-aisle/cold-aisle containment configurations where side coverage is needed but blocking cross-rack airflow would create thermal problems.
Key Features
- 42U Height Coverage: Spans the full height of a 42U rack frame — no stacking of partial panels, no gaps at top or bottom. A single pair covers the entire side of a standard 42U cabinet, keeping your installation clean and consistent.
- 1200mm Depth Sizing: Cut to match the 1200mm depth of the VR rack footprint exactly. Panels sized for 1100mm frames (see VRA6054) will not fit properly — verify your rack depth before ordering. If your Vertiv rack is 1100mm deep, the VRA6054 is the correct part.
- Pass-Through Construction: Unlike solid side panels, the pass-through design permits cable ingress and airflow laterally — important in multi-rack rows where inter-rack cabling or containment airflow management would be disrupted by fully solid panels.
- VR3300 / VR3350 Compatibility: Designed to mate with the Vertiv VR3300 and VR3350 open-frame rack platforms. These panels install without field modification on those frames. Confirm your base rack model before ordering — compatibility outside this family is not verified by evidence.
- Black Finish: Factory-finished in black to match the standard VR rack family aesthetic, keeping mixed-accessory deployments visually consistent in data center or IDF closet environments.
- Accessory Ecosystem Fit: Part of a broad Vertiv VR accessory line that includes split side panels (VRA6009/VRA6010), top panels (VRA6019/VRA6020), caster kits (VRA6024), and cable management brackets (VRA6025) — making it straightforward to fully enclose or partially enclose a VR rack with matched components from a single rack accessories family.
Integration and Compatibility
The VRA6055 is validated for use with the Vertiv VR3300 and VR3350 open-frame rack platforms at the 42U x 1200mm configuration. When planning a full enclosure build, pair these side panels with the VRA6019 or VRA6020 top panels (600mm or 800mm wide respectively) and the VRA6037–VRA6040 bottom panels for complete perimeter coverage. For split-panel installations — useful when rack access during a maintenance window requires panel removal from one section only — the VRA6009 and VRA6010 offer a two-piece alternative for 42U frames. The VRA6054 covers the same 42U height for 1100mm-depth racks if your row has mixed depths. Integrators building out data center infrastructure with standardized VR frames can source the complete panel and accessory set from this family without cross-brand fitment concerns.
Frequently Asked Questions
Q: What is the difference between the VRA6055 and the VRA6054?
A: Both are 42U pass-through side panels. The VRA6054 is sized for 1100mm-depth VR racks; the VRA6055 fits 1200mm-depth frames. Ordering the wrong depth will result in improper fit — measure your rack depth before purchasing.
Q: Which Vertiv rack models does the VRA6055 fit?
A: The VRA6055 is compatible with the Vertiv VR3300 and VR3350 open-frame rack platforms in the 42U x 1200mm configuration. Compatibility with other Vertiv rack lines is not confirmed by available evidence.
Q: Can the VRA6055 be used in hot-aisle/cold-aisle containment setups?
A: The pass-through construction allows airflow and cable paths to remain unobstructed laterally, making these panels more suitable for containment environments than solid side panels. Specific airflow ratings or containment certifications are not documented in available evidence — consult your thermal model for final validation.
Q: Are there equivalent panels for 48U racks?
A: Yes. The VRA6031 covers 48U x 1100mm and the VRA6032 covers 48U x 1200mm in the same pass-through style.
Q: Does the VRA6055 come as a single panel or a pair?
A: Available evidence does not specify whether the VRA6055 ships as a single panel or a matched pair. Confirm quantity per order with your supplier before purchasing to avoid under-ordering for a two-sided installation.
The VRA6055 is one of those parts that looks trivial until you order the wrong one — the 1200mm depth spec is the critical sizing detail here, and swapping a VRA6054 into a 1200mm-frame VR rack will give you a fitment problem on day one. I flag this specifically because the 1100mm and 1200mm variants look identical in catalog thumbnails.
Technical Highlights:
- Pass-Through Design (42U span): Full 42U height coverage without blocking lateral cable or airflow paths — this is the meaningful difference versus a solid blanking panel in any row where inter-rack cabling or containment airflow runs side-to-side.
- 1200mm Depth Match: Precision-sized to the VR3300/VR3350 1200mm frame — these panels install flush without shimming or field trimming, which matters when you are closing out multiple racks in a single maintenance window.
- VR Ecosystem Alignment: Pairs directly with VRA6019/VRA6020 top panels and VRA6037–VRA6040 bottom panels for complete perimeter enclosure using matched Vertiv components, avoiding cross-brand fitment guesswork.
Deployment Considerations:
- Confirm rack depth is 1200mm, not 1100mm, before ordering — the VRA6054 is the 1100mm counterpart and the two are not interchangeable on frame attachment points.
- Evidence does not confirm whether the VRA6055 ships as a single panel or a pair — verify quantity per SKU with your order to avoid a second shipment when closing both sides of a rack row.
The VRA6055 is the right call for facilities teams standardizing on the Vertiv VR3300 or VR3350 platform in 1200mm-depth rows who need pass-through side coverage without disrupting their containment airflow design — particularly in high-density IDF or data center builds where thermal management is already modeled around lateral airflow continuity.
