APC ACDC2551 - Enclosure Depth Adapter 600-750 mm

Overview

APC ACDC2551 is a mechanical depth adapter accessory designed to extend the usable depth of APC NetShelter enclosures. It is used by data center and rack infrastructure teams when reconfiguring or upgrading 42 U NetShelter cabinets to accept deeper equipment or containment components without compromising structural alignment.

This adapter allows adjustment of enclosure depth from 600 mm up to approximately 750 mm nominal, enabling support for deeper network devices, servers, or containment hardware that exceed the original cabinet depth specifications.

Mechanically, ACDC2551 is a rigid assembly that affixes to the existing rack structure and provides a stable extension platform. Its construction is suitable for typical server room and data center ambient conditions, designed to maintain cabinet integrity under load while preserving airflow and physical access.

The component is not an electrical, power, or network device. It does not perform any power distribution, environmental monitoring, or logical control functions; its role is strictly structural.

This accessory is not suitable as a standalone support for general shelving or non-APC enclosures. It is engineered for specific APC NetShelter depth extension use cases where compatible structural features are present.
