Overview

The APC AR7721 is a vertical cable management accessory designed for structured routing of power and data cables inside rack enclosures. It is used by data center engineers and network teams to maintain organized cabling in high-density rack environments.

This unit includes two vertical cable organizers with high-capacity finger designs that support cable separation, reduce strain, and maintain proper bend radius. It installs in a zero-U configuration, preserving all rack space for active equipment while improving airflow and serviceability.
