APC ACDC2518 Roof Height Adapter VX42U to SX48U, 750 mm | Rack Accessory

Maintain enclosure alignment when VX42U and SX48U rack systems need to meet at the roof line. The APC ACDC2518 roof height adapter is built for 750 mm integration, giving infrastructure teams a precise mechanical transition point between compatible rack formats. That matters when cabinet consistency, service access, and structural fit all have to stay predictable across the room. With a 28.9 in width, 46.9 in depth, and 7.6 in height, this adapter is sized for controlled placement in rack environments where tolerances matter. Its 62.46 lb approximate weight reflects a substantial hardware component intended for serious enclosure integration rather than light-duty accessory use. For teams managing mixed rack deployments, this adapter helps preserve layout discipline and supports a cleaner final installation. Choose this model when the cost of a mismatch is higher than the cost of getting the roof transition right the first time. It is a focused accessory for environments where enclosure compatibility, physical alignment, and installation confidence are part of the procurement requirement.
