APC ACDC2516 Roof Height Adapter SX42U to SX48U | Rack Accessory

Expand an SX42U enclosure to SX48U height without replacing the full rack system. The APC ACDC2516 roof height adapter is designed for controlled enclosure modification, giving infrastructure teams a precise way to accommodate taller configurations while maintaining the structural intent of the original platform. At 1,016 mm wide, this adapter is sized for the SX enclosure family and supports clean integration into planned rack builds. That matters when cabinet standardization, aisle consistency, and deployment timing all affect the cost of a project. Instead of moving to a larger enclosure footprint, teams can adapt the existing platform and preserve the surrounding layout. For data center refreshes, staged expansions, and site-specific buildouts, this accessory helps keep the rack architecture aligned with the rest of the room. It is a practical choice when the requirement is not just more space, but a controlled transition to a taller enclosure profile with APC fit and finish.
