Ortronics MM20CTB6H4PRU-B Cable Tray 6 in 4-post

Product Description

The ORTRONICS MM20CTB6H4PRU-B is a bottom-mount cable tray designed for use with 4-post open-frame racks. It provides a structured horizontal pathway for routing and managing data cables within a rack enclosure. The tray mounts beneath the rack to keep cable bundles organized, reduce strain on patch panel connections, and maintain clean airflow through the cabinet. Installation is handled by network or low-voltage structured cabling technicians. With a 6-inch depth profile, it accommodates moderate cable volume without obstructing rack access from the bottom.

This cable tray is suited for data center, server room, and telecommunications room applications where 4-post rack systems are in use. It supports horizontal cable management between patch panels, switches, and other active equipment. The bottom-mount design is commonly used when overhead or side cable management is not practical or when cable runs exit through a raised floor. Compatible 4-post rack environments typically include standard 19-inch equipment bays.

Key Features

• Bottom-mount cable tray for 4-post open-frame rack installations
• 6-inch depth accommodates mid-volume cable bundles
• Provides organized horizontal cable routing below rack-mounted equipment
• Reduces stress and strain on patch panel and equipment connections
• Supports clean cable egress for raised-floor environments

Compatibility

Designed as an OEM-style cable management accessory for standard 4-post open-frame rack systems commonly used in structured cabling and data center installations.

Installation Notes

Installation is typically performed by a licensed low-voltage or structured cabling technician. Power down all active equipment in the rack before beginning hardware modifications to avoid accidental disconnection or equipment damage. Secure all mounting hardware fully before routing cables through the tray. Follow TIA-568 and local building codes for structured cabling pathways and bend-radius requirements.
