Vertiv ESC-K12 Cable Management Fingers 7RU x 4in Deep — Qty 12

Overview

The Vertiv ESC-K12 is a horizontal cable management finger set sized at 7RU with a 4-inch depth, supplied in a quantity of 12. These fingers mount to the vertical cable management channels inside Vertiv rack enclosures, creating discrete horizontal lanes that guide and restrain patch cables, power cords, and data runs between adjacent equipment. Without structured finger sets, dense rack deployments accumulate cable mass that blocks airflow, complicates troubleshooting, and creates strain points at equipment ports — the ESC-K12 addresses all three by providing fixed routing lanes at consistent intervals across 7 rack units.

Compatibility

The ESC-K12 is designed for use with Vertiv rack enclosures and vertical cable management accessories in the ESC product family. These fingers are intended for integration with Vertiv's structured cabling accessories within compatible open-frame and enclosed rack systems. Verify your specific enclosure model supports the ESC finger mounting rail before ordering — rack enclosures from other manufacturers are not confirmed compatible.

Installation Notes

Install the finger units into the vertical cable management rail slots at the desired RU positions before populating equipment, as access becomes restricted once patch panels and switches are in place. Route cables through the fingers at each horizontal tier; avoid over-filling individual lanes, which can collapse the finger structure and negate the strain-relief benefit. The 4-inch depth accommodates moderate cable bundle diameters typical of patch panel and switch deployments; very high-density fiber runs may require a deeper channel. Each unit in the 12-piece set is identical — plan finger placement to align with equipment port rows for the cleanest horizontal runs. No special tools are required for mounting, but a cable management plan drawn before installation saves rework in live racks.
