Middle Atlantic MRK-2431LRD – 24SP Multibay MRK Rack 31"D with LRD

Product Overview

The Middle Atlantic MRK-2431LRD is a 24-space multibay MRK rack with a 31-inch depth and Middle Atlantic's Lever-Release Door (LRD) system, combining the accessibility advantages of mid-height rack configurations with the fast door access of the LRD mechanism. The 31-inch depth extends the equipment compatibility of this MRK variant, accommodating deeper AV and IT equipment that does not fit in 26-inch frames. The LRD system allows single-handed, tool-free door access, reducing maintenance time in operational AV environments. This rack is designed for gangable multibay deployments in AV equipment rooms where equipment depth requirements exceed the standard 26-inch configuration.

Product Description

The MRK-2431LRD addresses the need for a mid-height multibay rack that can accommodate deeper equipment — such as larger power amplifiers, high-density patch panels, and deeper network switches — without moving to a full 40U configuration. The 24U height keeps the rack at an operator-accessible level, which benefits installations where technicians need frequent access to equipment and ladder use is impractical or undesirable. The 31-inch depth adds approximately 5 inches over the standard 26-inch MRK, providing clearance for equipment that would otherwise require rear extension rails or repositioning. The LRD mechanism delivers operational efficiency in high-access environments: the door releases with a single lever action, requiring no tools and allowing one-handed operation. The multibay gangable design allows the MRK-2431LRD to be coupled with adjacent MRK units of the same depth, sharing structural support and enabling coordinated cable management and aesthetic uniformity across the rack row. Middle Atlantic MRK frames are built from heavy-gauge steel with welded bases for reliable performance under full equipment loads. Available through Creation Networks at creationnetworks.net.

Frequently Asked Questions

What is the difference between the MRK-2426 and MRK-2431LRD?

The MRK-2431LRD has a 31-inch depth (versus 26 inches on the MRK-2426) and includes the LRD door system. The deeper frame accommodates equipment that does not fit within the 26-inch configuration.

Can the MRK-2431LRD be ganged with MRK-2426 units?

Ganging MRK units of different depths requires careful planning. Contact Creation Networks for compatibility guidance before mixing depths in a rack row.

Is the LRD door available as a retrofit on existing MRK racks?

LRD functionality is specific to MRK models ordered with that door system. Contact Creation Networks to discuss retrofit options.

Where can I purchase the MRK-2431LRD?

It is available through creationnetworks.net.
