Ortronics MM20CT4RU-B Cable Trough 4U 19 Inch Black

Product Description

The ORTRONICS MM20CT4RU-B is a horizontal cable management trough designed for structured cabling and data center rack installations. Sized at 4U and 19 inches wide, it mounts in standard 19-inch EIA equipment racks to organize and route patch cables, power cords, and low-voltage wiring. The trough keeps cable bundles separated from active equipment, reduces strain on connector ports, and supports neat, serviceable runs across the rear or front of a rack. IT infrastructure technicians and low-voltage cabling contractors are the typical installers. The black finish blends with standard rack equipment in server rooms, telecom closets, and network distribution frames.

This cable management trough is suited for horizontal cable routing in 19-inch rack enclosures found in commercial and enterprise environments. It fits rack installations where organized cable management is required at the patch panel level, helping maintain airflow and access to equipment in densely populated racks. It is sold as a single unit and is appropriate for new rack builds as well as retrofit cable management upgrades in existing installations.

Key Features

• 4U rack height accommodates substantial cable volume in a single horizontal run
• 19-inch width fits standard EIA 19-inch rack and cabinet enclosures
• Black finish coordinates with standard rack-mounted equipment
• Horizontal trough design keeps cable bundles contained and routed away from active ports
• Single-unit quantity per package for individual rack buildouts or targeted replacements

Compatibility

Designed as an OEM-style cable management accessory for standard 19-inch EIA equipment racks and open-frame rack enclosures used in structured cabling installations.

Installation Notes

Low-voltage cabling technicians or IT infrastructure installers typically mount this trough during rack assembly or cable management retrofits. Power down or de-energize adjacent active equipment before routing cables through the trough to avoid accidental disconnection. Follow TIA-568 and local low-voltage wiring codes for cable bend radius and fill requirements. Avoid overfilling the trough, as excessive cable density can restrict airflow and make future service difficult.
