APC ACDC2500 Roof Height Adapter 300 mm for 42U SX | Rack Accessory

Keep aisle containment geometry aligned when moving from 42U SX to 42U rack configurations. The APC NetShelter Aisle Containment Roof Height Adapter is designed for 300 mm roof height adaptation, helping preserve enclosure fit and containment continuity in dense data center rows. This accessory is built for environments where small dimensional mismatches can compromise installation speed or containment integrity. Its black finish matches APC NetShelter systems, while the 42.1 in width and 3 in height support a defined roof interface for compatible deployments. At approximately 16.78 lb, it has the mass and structure expected of a purpose-built rack accessory rather than a generic filler component. For infrastructure teams standardizing APC containment systems, this adapter helps keep installations consistent across mixed rack heights and enclosure transitions. It is a practical choice when you need the right part to complete a containment run without improvisation.
