APC ACDC2509 Roof Height Adapter SX42U to SX45U | Rack Accessory

Preserve the enclosure you already standardized on while adapting it to a taller roof profile. This APC Schneider Electric roof height adapter is built for SX42U to SX45U conversion, giving infrastructure teams a precise way to match changing space, airflow, or integration requirements without moving to a new rack platform. At 1016 mm, the adapter is sized for controlled fitment in APC enclosure environments where dimensional accuracy matters. The black finish keeps the installation visually consistent with adjacent hardware, while the 45.92 lb approximate weight reflects a substantial structural component rather than a light trim piece. For data center teams, that matters: this is the kind of accessory chosen when enclosure geometry must be corrected cleanly and predictably. Use it when a deployment calls for a roof height change that must align with the rest of the rack system. It is a practical option for planned upgrades, enclosure standardization, and site-specific mechanical adjustments where replacing the full cabinet would add cost and disruption.
