Panduit CMUT19 Upper Cable Routing Trough

The Panduit CMUT19 is a 2 RU upper cable routing trough engineered for datacenter and server-room installations where vertical cable pathways terminate at the top of the rack. Measuring 4.5 inches deep, this trough provides ample capacity for high-density fiber and copper bundles while enforcing proper bend radius throughout the transition from vertical managers to horizontal distribution. Compatible with any EIA standard 19-inch rack or cabinet, the CMUT19 mounts directly to the top rail and eliminates the cable-sag and stress-concentration failures common in unsupported overhead spans.

Key Features

2 RU Height, 4.5" Depth: Accommodates large cable counts and maintains ANSI/TIA-568 minimum bend radius for Cat6A, fiber trunk, and power distribution

Universal EIA 19" Rack Compatibility: Mounts to any standard rack top rail without adapters or modification

Black Powder-Coat Finish: Matches industry-standard rack aesthetics and resists corrosion in temperature-controlled environments

RoHS Compliant Construction: Meets EU and California environmental restrictions for equipment deployed in regulated facilities

Single-Unit Packaging: One trough per carton for precise inventory control on multi-rack deployments

The CMUT19's 3.5-inch overall height (88.9 mm) and 19-inch width (483 mm) align with standard rack increments, consuming exactly two rack units when installed. The 4.5-inch depth extends forward from the mounting plane to create a cable basin with sufficient volume for 48-strand fiber trunk cables, multiple Cat6A patch bundles, or mixed-media runs that include DC power feeds to top-of-rack switches. Unlike shallow troughs that force installers to overfill and compress cables into tight radii, the CMUT19's depth allows natural cable lay and prevents the jacket deformation that leads to insertion loss in fiber and return-loss degradation in copper. The trough's open-top design permits cables to enter and exit at any point along its length, supporting both linear rack-to-rack pathways and radial distribution to overhead cable tray.

In practice, the CMUT19 solves the cable-exit problem at the top of high-density racks where vertical managers terminate. When 42U racks house blade servers, ToR switches, or fiber aggregation chassis, dozens of cables converge at the top rail with nowhere to transition horizontally. Without a trough, cables drape over the rail edge, creating stress points that fracture fiber cores or kink Cat6A conductors. The CMUT19 captures these cables in a supported pathway, spreading the load across the trough's base and maintaining the 1-inch minimum bend radius required by TIA-568.2-D. The trough's black finish integrates visually with APC NetShelter, Chatsworth, Panduit Net-Access, and other commercial rack lines, preserving the clean appearance required in customer-facing colocation suites and executive datacenter tours.

The CMUT19 ships RoHS compliant, making it suitable for installations in the European Union, California state facilities, and any environment governed by hazardous-substance restrictions. For integrators managing cable-plant upgrades in active datacenters, the single-unit packaging simplifies logistics—order one CMUT19 per rack rather than dealing with multi-pack SKUs that leave unused inventory. Pair with Panduit's WYR-series vertical managers and CMDAG finger ducts to build a complete rack cable-management system that meets TIA-942 Rated-3 and Rated-4 datacenter tier standards.
