Middle Atlantic C5-MK27-3 27U 3-Bay Rack Mounting Kit
Overview
The Middle Atlantic C5-MK27-3 is a mounting worktop kit designed for the C5 series rack enclosure line, configured for 27-space (27U) frames in a 3-bay arrangement. Rack build-outs in AV, security, and IT infrastructure often require supplemental mounting hardware to properly join, anchor, or finish multi-bay enclosure runs — the C5-MK27-3 provides the manufacturer-matched hardware to complete that assembly without resorting to field-fabricated solutions that compromise alignment and structural integrity. If you are specifying a C5 enclosure system at the 27U height in a 3-bay configuration, this kit supplies the dedicated mounting components designed alongside the enclosure rather than adapted to it.
Compatibility
The C5-MK27-3 is designed for use with Middle Atlantic C5-series rack enclosures at the 27U frame height in 3-bay deployments. Verify your enclosure model designation against the C5 series before ordering — Middle Atlantic's rack enclosure product line spans multiple frame heights and bay counts, and mounting kits are not interchangeable across frame sizes. If your installation uses a different U-height or a 2-bay or 4-bay configuration, a different MWK suffix variant will be required. Consult Middle Atlantic's C5 rack accessories documentation to confirm the correct kit for your specific frame combination before procurement.
Installation Notes
As with all rack mounting hardware in the C5 family, install this kit per Middle Atlantic's assembly sequence for multi-bay frames — incorrect installation order can prevent proper alignment of adjoining bays. Confirm mounting surface load ratings and floor anchor requirements for the completed enclosure run. For rack system deployments in seismic zones or high-vibration environments, verify compliance with applicable local codes before finalizing the enclosure anchor method.
