42U Expansion Enclosure for Bayed Racks

This 42U SmartRack expansion cabinet is built for data-centre rows where multiple enclosures are bayed together. It ships without side panels so adjacent units share a common wall, saving floor space while keeping the full 42U of vertical mounting capacity.

Fully Assembled Frame with Locking Doors

The unit arrives fully assembled on four interior vertical posts with unthreaded square-hole openings that meet the EIA-310-E standard. Locking, removable and reversible front and rear doors provide secure access, while the open sides deliver massive front-to-rear airflow across the 24-inch-wide chassis.

Verify Baying Plans and Floor Load Before Ordering

Confirm that your layout calls for side-by-side baying, because this model includes no side panels and cannot stand alone as a finished cabinet. The floor must support 3000 lbs stationary or 2250 lbs rolling per enclosure, and the 78.5-inch height requires adequate ceiling clearance.
