APC by Schneider Electric AR7055 NetShelter SX 45U 750mm Perforated Curved Door
Overview
The AR7055 is a factory-replacement perforated curved front door designed specifically for APC by Schneider Electric NetShelter SX 750mm-wide, 45U rack enclosures. If your existing door is damaged, missing, or you are commissioning a NetShelter SX frame that shipped without one, the AR7055 restores the enclosure to its original specification without modification or improvisation. At 2044mm tall and 750mm wide, it matches the full height of a 45U NetShelter SX chassis and integrates with the existing hinge and latch hardware already on the frame.
The perforated panel design is not cosmetic — open perforation across the door face allows front-to-rear airflow through the enclosure. In densely populated rack enclosures running active cooling, restricting inlet airflow at the door is one of the most common causes of thermal events. The curved profile maintains clearance between the door surface and installed equipment, reducing the risk of accidental contact with front-panel connectors, cable management, and patch panel ports during routine access.
Key Features
- 45U height, 750mm width (2044mm × 750mm × 35mm): Dimensioned to the NetShelter SX 750mm chassis standard — no cutting, shimming, or custom hardware required. Ordering the wrong door width is a common and expensive mistake; this fits the 750mm rail width specifically, not the 600mm or 800mm variants.
- Perforated curved panel: Perforation supports front-to-rear airflow, critical in any data center infrastructure deployment where inlet air restriction drives hot spots. The curved geometry creates a small buffer zone between the door interior and rack-mounted equipment, reducing incidental contact risk during access.
- Factory color match — Black: Matches the standard NetShelter SX black finish. Relevant in co-location environments and enterprise data centers where rack uniformity is an operational or contractual requirement.
- Designed for NetShelter SX compatibility: Mounts directly to existing NetShelter SX hinge and latch points. No adapter plates, no third-party hardware. The AR7055 restores the enclosure to its original manufactured configuration.
- Packaged for freight (845mm × 120mm × 2140mm, 18 kg): Factory packaging dimensions confirm the door ships as a single flat parcel. At 18 kg (approximately 39.7 lbs), standard LTL freight handling applies — plan for two-person installation or a lift-assist on raised-floor environments.
Integration & Compatibility
The AR7055 is designed exclusively for the APC NetShelter SX enclosure line in the 750mm-wide format. Before ordering, confirm your enclosure is a NetShelter SX (not NetShelter EP, NetShelter VX, or a third-party frame) and that the rail width is 750mm. APC produces NetShelter SX doors in multiple widths — 600mm and 800mm variants use different door part numbers and are not interchangeable with the AR7055. Verify your existing frame's width specification on the enclosure nameplate or procurement records before placing an order.
For facilities managing multiple rack enclosures, rack accessories such as cable management arms, blanking panels, and side panels are also available for the NetShelter SX line and can be deployed alongside the AR7055 to complete a full enclosure refresh.
Frequently Asked Questions
Q: What enclosure does the AR7055 fit?
A: The AR7055 is designed specifically for APC NetShelter SX 750mm-wide, 45U enclosures. It is not compatible with NetShelter EP, NetShelter VX, or non-APC rack frames.
Q: Is the AR7055 compatible with 600mm or 800mm NetShelter SX enclosures?
A: No. APC produces NetShelter SX doors in multiple widths. The AR7055 is the 750mm variant only. Ordering the wrong width will result in a door that does not fit the hinge and latch points on the frame. Confirm your enclosure's rail width before ordering.
Q: Does the AR7055 include mounting hardware?
A: The AR7055 is a replacement door designed to mount to existing NetShelter SX hinge and latch hardware already present on the enclosure. No additional mounting hardware is specified in the available product data — contact your pre-sales team if your frame is missing hinge components.
Q: What does the perforated design mean for airflow?
A: The perforated panel allows front-to-rear airflow through the enclosure, which is important for maintaining proper cooling in actively ventilated racks. A solid door in the same position would restrict inlet airflow and increase thermal risk in densely populated enclosures.
Q: What is the shipping weight of the AR7055?
A: The packaged weight is 18 kg (approximately 39.7 lbs). Package dimensions are 845mm wide × 120mm deep × 2140mm tall. Plan for two-person handling or lift-assist equipment, particularly in raised-floor data center environments.
The AR7055 is the kind of part that gets overlooked until it creates a problem — a damaged or missing front door on a NetShelter SX 45U frame is more than a cosmetic issue. At 2044mm × 750mm, this door spans the full height and width of the 750mm NetShelter SX chassis, and the perforated curved panel is doing real thermal work in any rack where active cooling depends on consistent front-inlet airflow.
Technical Highlights:
- Exact 750mm fitment: The AR7055 is width-specific — it will not swap with 600mm or 800mm NetShelter SX doors. Mismatched widths won't align to the existing hinge mounts, which means you need the correct part number before the frame goes back into service.
- Perforated curved profile (35mm depth): The 35mm door depth creates a small but meaningful air gap between the door interior and front-panel equipment. In high-density rows, this reduces accidental disconnection of patch cables and front-panel interfaces during routine access — a small detail that matters in production environments.
- Package weight 18 kg: At 39.7 lbs in a 2140mm-tall package, this ships as a single flat freight item. Two-person lift is the practical minimum; in raised-floor facilities with limited staging space, plan accordingly before delivery.
Deployment Considerations:
- Confirm enclosure nameplate or procurement records show NetShelter SX 750mm before ordering — APC offers visually similar doors for 600mm and 800mm frames under different part numbers, and returns on oversized freight parts are operationally painful.
- The AR7055 mounts to existing hinge and latch hardware on the frame. If the frame's hinge points are also damaged, the door alone will not resolve the issue — assess the frame hardware before ordering only the door.
This is the right part for a NetShelter SX 750mm, 45U frame that needs a factory-spec front door restored — whether that is a co-location cage refresh, a post-incident repair, or completing a used-frame purchase that arrived without a door.
