APC by Schneider Electric AR7057A NetShelter SX 48U 750mm Perforated Curved Door
Overview
The AR7057A is a factory-replacement curved perforated front door designed for APC NetShelter SX 48U rack cabinets with a 750mm wide footprint. At 85.9" tall and 29.5" wide, it matches the full enclosure face — this is not a universal door, it is a direct-fit component for that specific enclosure. The curved perforated design allows front-to-rear airflow to pass through without obstruction, which matters in densely loaded racks where restricted airflow translates directly to thermal problems and hardware throttling. If your deployment has a damaged, missing, or upgraded-away door on a NetShelter SX 48U 750mm chassis, AR7057A is the correct replacement part.
Compatibility
Designed exclusively for the APC by Schneider Electric NetShelter SX 48U rack enclosure family in the 750mm wide configuration. This door does not fit NetShelter SX enclosures with 600mm or 1200mm widths, nor does it fit NetShelter VX or NetShelter EP chassis — dimensional and hinge geometry differ across those lines. Verify your existing rack cabinet is the 750mm-wide SX 48U variant before ordering. The black color matches standard NetShelter SX black-frame deployments.
Installation Notes
Door weight is 30.75 lb — have a second person on hand during swap to manage the hinge alignment safely. The AR7057A is RoHS-compliant, making it suitable for installations in jurisdictions with Restriction of Hazardous Substances requirements. No additional tools or hardware are specified in evidence beyond standard rack-door hinge pins.
