Middle Atlantic MK-LA Ladder Adapter Top for MK Series Racks

Overview

The MK-LA is a Middle Atlantic cable ladder top adapter designed specifically for MK Series open-frame racks. It solves the common integration challenge of routing high-density cabling out the top of a rack enclosure in an organized, code-friendly manner — particularly in AV, security, and network equipment rooms where overhead cable runs are standard. At 34 in tall and 19 in wide, the MK-LA fits standard 19-inch rack topography and provides a structured pathway that keeps cables separated from active equipment and accessible for future moves, adds, and changes. If you're building out a rack accessory package for a new MK Series installation, this adapter ships direct and pairs naturally with the rest of the MK top-of-rack ecosystem.

Compatibility

The MK-LA is designed for use with Middle Atlantic MK Series open-frame racks. It is not a universal cable ladder — confirm your rack is MK Series before ordering. The 19-inch width aligns with standard EIA-310 rack rail spacing, making it dimensionally consistent with 2-post and 4-post MK Series configurations. For projects requiring seismic compliance, the MK-LA carries a seismic rating — a meaningful spec in California Title 24, OSHPD, or data center environments where rack anchoring and top-of-rack hardware must meet shake-table certification. If your project spec sheet calls out seismic-rated infrastructure, this satisfies that requirement at the top adapter level. Finish is black powder coat, consistent with standard Middle Atlantic MK Series rack aesthetics. For broader network rack enclosure options or additional cable management components, verify compatibility with your specific MK rack model before combining accessories.
