Vertiv 8402E-MCH24SL-B ES Series Hex Mesh Cabinet Door Seal
The Vertiv 8402E-MCH24SL-B is a hex mesh door seal panel designed for the Vertiv ES series rack enclosure line, sized specifically for 84-inch-tall, 24-inch-wide cabinet configurations. If you are outfitting an ES series cabinet and need to close off the front door gap while maintaining airflow, this is the part to specify.
Overview
The 8402E-MCH24SL-B ships in black and is matched to the 84-inch cabinet height across ES series frames. The hex mesh pattern allows passive airflow through the door panel without leaving large open gaps — a practical balance between cable access management and containing cold aisle airflow in structured deployments. This part number (often searched as 8402E MCH24SL B) targets the 24-inch-width front door position within the ES cabinet family.
Compatibility
This seal is designed for Vertiv ES series cabinets in the following verified configurations:
- Cabinet height compatibility: Fits 79-inch, 84-inch, and 91-inch ES series frames — confirm your exact cabinet height before ordering; the seal dimension is sized for the 84-inch door opening on this SKU.
- Cabinet width: 24-inch width for the front door position; the ES family also offers 30/32-inch front and rear door variants under separate SKUs — verify your cabinet width to avoid a mis-order.
- Color: Black finish, matching standard Vertiv ES series black enclosures. Clear and other color variants exist in the product family for mixed-finish or visibility requirements.
Installation Notes
This is a rack cabinet accessory intended as a direct replacement or add-on panel for existing ES series door frames. No tools or special hardware are described in available evidence — confirm mounting method with your ES cabinet documentation before installation. This part does not alter the structural rating or thermal specifications of the cabinet itself; it is a passive mesh seal only.
