APC AR7508 NetShelter SX 42U Recessed Rail Kit | Rack Mount

Build a cleaner, more controlled rack layout inside compatible NetShelter SX enclosures. The APC AR7508 recessed rail kit is designed for 42U, 750 mm wide NetShelter SX enclosures, giving integrators the mounting structure needed to position equipment with a recessed profile. That extra clearance can make a difference when planning airflow, cable routing, and front-to-back access. This kit is more than a simple rail set. It includes the mounting hardware and tools required to complete the installation, including Torx screws, cage nuts, vertical mounting rails, vertical mounting flanges, a cage nut tool, and a Torx T30/#2 Phillips wrench. For teams standardizing on APC enclosure systems, that means fewer missing parts, less time spent sourcing hardware, and a more predictable install. The recessed profile supports denser, cleaner rack builds where equipment alignment and enclosure fit are critical. With RoHS compliance, a 2-year warranty, and compatibility targeted to a specific enclosure class, the AR7508 is built for deployments where precision matters more than generic fit.
