APC ACDC2505 Roof Height Adapter SX42U to SX45U 300 mm | Rack Accessory

When a rack design needs more vertical clearance, the APC Roof Height Adapter provides a precise path from SX42U to SX45U. This 300 mm adapter is built for enclosure integration, helping teams match roof height requirements without reworking the broader rack plan. In dense infrastructure environments, that kind of fit control saves time during deployment and reduces friction during expansion. The adapter’s black finish keeps the installation visually consistent with surrounding APC hardware, while its direct-ship format supports procurement workflows that need a defined, single-purpose component. At approximately 23.13 lb, it has the substance expected from a structural rack accessory rather than a lightweight add-on. For data center teams standardizing enclosure geometry, this part helps maintain clean mechanical alignment across the rack system. It is a practical choice when the enclosure must move from one roof height profile to another without compromising the overall installation plan.
