Middle Atlantic RIB-5-MRK-31 Riser Base for VMRK Racks

The Middle Atlantic RIB-5-MRK-31 is a purpose-built riser base designed to sit beneath five-bay VMRK Series rack configurations with a 31-inch depth. Constructed from 1/8-inch thick fully welded steel, it delivers a rock-solid foundation that keeps your rack system stable and level. The durable black powder coat finish provides corrosion and scratch resistance while maintaining a professional appearance that blends seamlessly with standard rack hardware.

Beyond structural support, the RIB-5-MRK-31 serves a practical secondary role as a lower cable chase. The open design beneath the rack allows installers to route power and data cables cleanly underneath the system, reducing visible cable clutter and improving airflow. Standing just 2.5 inches tall and weighing 16 pounds, it adds minimal bulk while providing meaningful clearance for cable management in server rooms, AV installations, and broadcast environments.
