APC ACDC2552 Depth Adapter, 600 mm, 42U | NetShelter, Aisle Containment

Keep containment geometry consistent when rack depths vary across the row. The APC NetShelter Aisle Containment Depth Adapter is designed for 42U VX enclosures and supports 900 to 1,200 mm rack depths with a 600 mm width profile. That makes it a practical fit for data centers standardizing around APC NetShelter containment while accommodating mixed cabinet depths, phased expansions, or retrofit projects. By preserving the intended spacing between enclosure and containment structure, this adapter helps maintain airflow discipline and reduces the compromises that come with improvised fitment. It is a purpose-built accessory for teams that need repeatable installation outcomes, not a generic spacer. The compact 2.6 in profile and approximately 12.19 lb weight keep the component manageable during deployment, while the RoHS-compliant design aligns with procurement and sustainability requirements. For infrastructure teams, the value is in consistency: fewer field adjustments, cleaner integration, and a more controlled containment environment across the rack row. When aisle containment has to match the rack plan instead of forcing the rack plan to match the containment, this adapter closes the gap.
