Middle Atlantic RIB-5-MRK-36 – 5-Bay MRK Riser Base 36"D

Product Overview

The Middle Atlantic RIB-5-MRK-36 is a 5-bay riser base kit for MRK series rack systems with a 36-inch depth, designed to elevate a row of MRK racks off the floor and establish a dedicated under-rack cable routing zone. By raising the rack row, this riser base creates structured clearance beneath the equipment for power cables, low-voltage signal runs, and structured cabling that would otherwise compete for space within the rack or behind it. The 36-inch depth matches MRK rack footprints in that configuration, ensuring a flush and aligned installation. This accessory is a standard component in high-density AV infrastructure buildouts where cable management is a design priority.

Product Description

Cable management in multibay MRK rack deployments benefits significantly from under-rack routing, which separates power and signal cables from the rack interior and provides a clean, accessible pathway for cable runs to adjacent bays, floor conduits, or raised-floor systems. The RIB-5-MRK-36 delivers this capability as a factory-engineered riser base that spans a full 5-bay MRK row and provides a consistent elevation across the entire installation. The 5-bay span eliminates the need for individual riser elements under each bay, providing a unified base structure that simplifies installation and provides a consistent finished appearance. The 36-inch depth matches the MRK rack footprint in that configuration, ensuring proper alignment between the riser base and the rack frames above it. Construction is heavy-gauge steel, providing the load-bearing capability required to support fully populated MRK rack rows. The riser base integrates with MRK rack leveling and anchoring systems, enabling proper floor anchoring in both non-raised and raised-floor environments.

Frequently Asked Questions

How does the RIB-5-MRK-36 differ from the RIB-5-GRK-36B?

The RIB-5-MRK-36 is designed for MRK series racks, while the RIB-5-GRK-36B is designed for GRK series racks. They share the same riser base concept but are engineered for their respective rack series mounting interfaces.

Does this riser work with all MRK rack heights?

The riser base is depth-specific (36 inches). It is compatible with MRK racks of that depth configuration regardless of rack unit height. Verify your rack depth before ordering.

Can the riser be anchored to the floor?

Yes. The riser integrates with MRK rack leveling and anchoring hardware. Consult Middle Atlantic's installation documentation for anchoring requirements specific to your environment.

Where can I purchase the RIB-5-MRK-36?

It is available through creationnetworks.net.
