APC AR3357 NetShelter SX 48U

Pre-installed full-enclosure height rear accessory channels
Integrated and adjustable rear accessory channel provides zero U mounting locations for toolless accessories. Each channel has two mounting bays to support a combination of up to four accessories such as PDUs and vertical cable organizers. 1070mm (42in), 825mm (32 in), and deep enclosures and networking enclosures include two channels. 1200mm (48in) deep enclosures include four channels. Channels are pre-installed at the factory in the rear of the enclosure but can be moved to other locations of the enclosure along the side brace to resituate cable management where it is needed most.

Adjustable mounting rails with captive hardware and rapid alignment
The vertical mounting rails can be adjusted in 1/4 in (6.4 mm) increments covering virtually any mounting requirement for IT equipment. Easy alignment feature integrated into the enclosure mounting rail and side brace for quick alignment verification without the use of tools to verify alignment. U positions are numbered front and back for rapid installation of equipment.

Split rear doors
Split rear doors improve access and serviceability to rear of rack mounted equipment. The split rear doors help to maximize floor space. Only 11 inches (279 mm) of clearance is required behind the enclosures to allow for door swing.

Low-profile castors and adjustable leveling feet from underneath or above
Enclosures are shipped standard with both leveling feet and castors. Leveling feet can be quickly adjusted through the use of a screwdriver or drill, eliminating the need to reach underneath with a wrench.

Integrated joining hardware with multiple width enclosure alignment
Enclosures include pre-installed joining hardware to join enclosures in a row and provide additional stability to the enclosure. The pre-installed joining hardware includes holes for joining to an adjacent enclosure at 600mm centers or 24in centers depending upon the floor layout.
