Ortronics MM20842ADJ12-B 4-post 42U Adjustable Rack

Product Description

The ORTRONICS MM20842ADJ12-B is a 4-post, open-frame adjustable rack designed for structured cabling and network equipment installations. Standing 42U tall at 8 feet, this rack provides a rigid, adjustable-depth mounting framework for patch panels, switches, servers, and related hardware. The adjustable rail design allows technicians to set the mounting depth to match the equipment being installed, reducing the need for extension brackets. This unit ships as a single rack assembly and is suited for data center, telecommunications room, and enterprise LAN closet deployments.

This rack is intended for low-voltage structured cabling and IT infrastructure applications in both commercial and enterprise environments. It is typically installed by low-voltage technicians, network infrastructure contractors, or data center facilities staff. The open-frame 4-post design allows unrestricted airflow and easy front and rear access to mounted equipment, making it a practical choice for high-density installations where cable management and equipment accessibility are priorities.

Key Features

• 42U capacity provides substantial mounting space for high-density equipment deployments
• 8-foot height accommodates full-height rack installations in standard ceiling-height telecom rooms
• Adjustable 4-post rail design supports variable equipment depths without additional hardware
• Open-frame construction allows unrestricted airflow and front-to-rear cable routing
• Single unit per package for straightforward procurement and installation planning

Compatibility

Designed as an OEM-style open-frame rack solution for structured cabling and network equipment installations requiring a 42U, 4-post adjustable mounting framework.

Installation Notes

Installation is typically performed by licensed low-voltage contractors or qualified IT infrastructure technicians. Ensure the floor surface is level and capable of supporting the combined weight of the rack and all mounted equipment before installation. All power to rack-mounted active equipment should be disconnected prior to servicing or repositioning rail assemblies. Local building and fire codes, including TIA-942 data center standards where applicable, should be consulted for proper rack placement, grounding, and cable management requirements.
