Lionbeam lb-sra-42812 42U Server Rack Cabinet Mesh Doors

Product Description

The LIONBEAM lb-sra-42812 is a 42U freestanding server rack cabinet designed for structured data center, server room, and network closet deployments. It ships with front and back mesh doors for passive airflow, eight integrated cooling fans, three equipment trays, and two vertical cable management panels. The cabinet measures 31.5 inches wide and 47 inches deep, providing the internal real estate required for standard 19-inch rack-mount equipment. Cage nut mounting rails support standard EIA-310 rack units throughout the full 42U height. This cabinet is installed by IT infrastructure technicians, low-voltage contractors, and network engineers.

The lb-sra-42812 suits medium-to-large server room builds where airflow management, cable organization, and physical equipment security are priorities. The mesh door design promotes front-to-back airflow without requiring perforated blanking panels to maintain pressure. The included trays accommodate unrackable equipment such as patch panel accessories, small UPS units, or ancillary networking devices. The vertical cable managers route patch cables and power cords along the sides of the cabinet interior, reducing obstruction in the main rack space. This unit ships crated for freight delivery, making it suitable for new construction and renovation projects.

Key Features

• 42U rack height supports a full complement of 1U through 4U server and networking equipment
• Front and back mesh doors promote front-to-back airflow and allow visual status checks without opening the cabinet
• Eight integrated fans assist active airflow management for high-density equipment loads
• Three included equipment trays provide shelf space for non-rack-mount devices
• Two vertical cable management panels route and organize patch cables and power cords along cabinet sides
• Cage nut rail system accommodates standard EIA-310 19-inch rack-mount equipment throughout the full 42U height
• Crated packaging protects the cabinet during freight shipment to job sites

Compatibility

Designed as an OEM-style enclosure for standard 19-inch EIA-310 rack-mount servers, switches, patch panels, and networking equipment in data center and server room installations.

Installation Notes

Installation is typically performed by low-voltage contractors or IT infrastructure technicians following TIA-942 or applicable local data center build standards. Position the cabinet with adequate clearance at the front and rear for door swing and airflow before anchoring to the floor. Power down all equipment before seating or removing rack-mount devices inside the cabinet. Verify floor load ratings prior to deployment, as a fully populated 42U cabinet can exceed structural thresholds in older buildings.
