Vertiv 8403E-SS29-B Split Solid Cabinet Door for 84" x 29–32" Enclosures
The Vertiv 8403E-SS29-B is a split solid door panel designed to fit Vertiv cabinet enclosures with an 84-inch height and a width of 29, 30, or 32 inches. Finished in black, it is a direct replacement or upgrade component for Vertiv rack enclosure systems where a solid (non-vented) door is required — common in environments where dust control, physical access restriction, or a cleaner visual presentation takes priority over front-panel airflow.
Overview
The 8403E-SS29-B is part of Vertiv's ES enclosure door line. The split-door configuration means the panel is divided into two sections, which simplifies removal and reinstallation in tight aisles or fully populated rows where swinging a full-height door panel is impractical. If you're retrofitting an existing Vertiv ES-series cabinet in a colocation cage or server room with restricted aisle clearance, the split design is the operational advantage that matters most here.
Compatibility is defined by two dimensions: cabinet height (84 inches) and cabinet width (29, 30, or 32 inches). Verify both before ordering — Vertiv ES cabinets are available in multiple height configurations (79", 84", 91", 98") and widths (24" and 29/30/32"), and door panels are not interchangeable across size families. The 8403E-SS29-B targets the 84" height and the wider 29–32" width class only.
The black finish (also noted as available in Other/Clear variants under the ES door family) matches standard Vertiv ES cabinet colorways and keeps the installation visually consistent in mixed-vendor rows where appearance uniformity matters to facilities teams.
Key Features
- 84" height compatibility: Fits Vertiv ES cabinets at the 84-inch height — the most common rack height in enterprise data center and IT closet deployments. Mismatching height will prevent proper hinge and latch alignment, so confirm your cabinet's U-height and physical height spec before purchase.
- 29–32" width range: The wider cabinet class in the Vertiv ES line. If your cabinet is 24" wide, this door does not apply — that width requires a separate SKU.
- Split solid panel: Two-section door construction reduces the swing arc needed for opening, making servicing feasible in tight aisles without pulling the cabinet forward. Solid (non-perforated) construction blocks incidental airflow through the door face — plan your cooling accordingly if front-to-back airflow is part of your thermal design.
- Black finish: Consistent with standard Vertiv ES cabinet colorways, relevant when visual uniformity across cabinet rows is a facilities or client requirement.
Compatibility
The 8403E-SS29-B (often searched as 8403E SS29 B) is designed exclusively for Vertiv ES-series cabinet enclosures. Confirm the following before ordering: (1) cabinet height is 84 inches, and (2) cabinet width is 29, 30, or 32 inches. This door will not fit 24" cabinets, nor will it fit 79", 91", or 98" height configurations. Cross-reference your existing cabinet model number against Vertiv's ES enclosure compatibility documentation to verify the correct door SKU for your specific unit. For network cabinets and rack enclosures, selecting the correct door dimensions is a prerequisite — Vertiv publishes compatibility tables by cabinet model that should be your primary reference.
Frequently Asked Questions
Q: What cabinet height does the 8403E-SS29-B fit?
A: The 8403E-SS29-B is designed for Vertiv ES cabinets with an 84-inch cabinet height. It is not compatible with the 79", 91", or 98" height variants in the ES line.
Q: What cabinet widths are compatible with the 8403E-SS29-B?
A: This door fits Vertiv ES cabinets in the 29", 30", and 32" width class. It does not fit 24"-wide cabinets, which require a separate door SKU.
Q: Is the 8403E-SS29-B a vented or solid door?
A: It is a solid door panel. It does not include perforations or mesh venting. If front-panel airflow is part of your thermal design, a vented door variant should be selected instead.
Q: What does "split" mean in the door description?
A: The split configuration means the door is divided into two separate panels rather than a single full-height sheet. This reduces the swing clearance needed to open the door — useful in narrow or congested aisles where a single full-height door would require pulling the cabinet out to service it.
Q: What color is the 8403E-SS29-B?
A: The 8403E-SS29-B ships in black, consistent with standard Vertiv ES cabinet finishes. Other color or clear variants exist in the ES door family under different SKUs.
The 8403E-SS29-B is a straightforward enclosure door, but the spec that actually matters at ordering time is the width range: 29–32 inches. Vertiv's ES line spans two width classes — 24" and 29/30/32" — and the door SKUs are not interchangeable. I've seen integrators order the wrong door simply because the height matched and they assumed width was close enough. It isn't. The hinge and latch geometry are specific to the width class.
Technical Highlights:
- 84" height targeting: Positions this door for the most common full-size enterprise rack height. The ES line also ships in 79", 91", and 98" — verify your cabinet's physical height spec, not just the U-count, before ordering.
- Split panel construction: Two-section design reduces the door swing arc, which is operationally significant in hot-aisle/cold-aisle containment rows where aisle width is at a premium.
- Solid (non-vented) panel: Zero airflow penetration through the door face. In a properly designed front-to-back airflow cabinet, this is fine — your perforated top or rear exhaust handles the exit path. In a poorly planned thermal setup, a solid front door can create a hot spot. Know your airflow before specifying solid vs. vented.
Deployment Considerations:
- Confirm both cabinet height (84") and width class (29/30/32") against your existing Vertiv ES cabinet model number before placing the order — Vertiv's ES door compatibility is dimension-strict, not approximate.
- Solid doors are not appropriate for high-density compute cabinets relying on front-panel intake airflow. If your cabinet houses active networking or compute gear with front-mounted fans, specify a vented door variant instead.
The 8403E-SS29-B is the right call for a Vertiv ES 84" x 29–32" cabinet in a physical security or access-control room where dust ingress and visual tidiness matter more than front-panel airflow — think telecom closets, surveillance head-end rooms, and access control equipment enclosures where the gear is passive or rear-vented.
