Middle Atlantic RIB-1-MRK-26 Riser Base

Timesaving and practical, the Raised Floor Enclosure System™ consists of 2-1/2" high riser bases, designed to streamline field rough-in procedures prior to the arrival of racks and enclosures. The RIB-1-MRK-26 raises equipment to the ideal height for clean cable management, making it easier to route, organize, and conceal cables in busy data centers, broadcasting facilities, and control rooms. This riser base also doubles as a lower cable chase in multi-bay installations, providing a dedicated path for cables to travel between racks without compromising airflow or accessibility. By enabling early rough-in and flexible future expansion, the RIB-1-MRK-26 helps technicians deliver professional, system-ready environments with less downtime and less rework. Whether you’re configuring a single rack or a multi-bay enclosure ecosystem, this riser base supports precise alignment, steady footing, and scalable cable management as your system grows.

• Time-saving field rough-in: The 2-1/2" riser height enables pre-assembly and rough-in procedures before racks and enclosures are delivered, reducing on-site installation time and minimizing disruption to existing workflows.
• Lower cable chase for multi-bay layouts: The raised base creates an integrated channel for routing power and data cables between bays, keeping cables organized and out of the way of equipment, while preserving clean sight lines and easy access during maintenance.
• Modular scalability for growing systems: Designed to work within Middle Atlantic’s Raised Floor Enclosure System, the RIB-1-MRK-26 supports scalable configurations—from a single rack to expansive multi-bay installations—without compromising performance or cable management.
• Enhanced stability and alignment: Built to provide a stable platform, the riser base helps ensure precise rack positioning, simplifying subsequent rack mounting and reducing misalignment risks during expansion or reconfiguration.
• Efficient installation workflow: The lightweight, purpose-built design facilitates quick placement and leveling, allowing technicians to stage cables and components in advance, then complete final assembly with minimal downtime.

How to install Middle Atlantic RIB-1-MRK-26 Riser Base

• Plan your layout by determining the number of riser bases required for your rack or multi-bay configuration, and identify alignment references to ensure consistent spacing.
• Place each riser base at the intended footprint, aligning with rack feet or mounting points to establish a stable, even foundation.
• Level the bases on the floor using shims or adjustable elements as needed to achieve a perfectly flat base, which is essential for rack stability and smooth enclosure mounting.
• Perform an initial rough-in by routing cables within the 2-1/2" height of the riser base area, leaving ample slack for future moves and ensuring compliance with local codes and organizational standards.
• In multi-bay configurations, connect adjacent riser bases to form a continuous cable chase between bays, then place racks and enclosures onto the base framework. Verify that cables are neatly organized and that airflow is unobstructed before final installation.

Frequently asked questions

• What is the RIB-1-MRK-26 used for? It is a component of Middle Atlantic’s Raised Floor Enclosure System that raises equipment to a practical height for field rough-in and provides a dedicated cable chase when installing multiple bays, simplifying cable routing and future expansion.
• What is the height of the riser base? The riser base is 2-1/2 inches tall, designed to create a low-profile yet functional platform for racks and enclosures while enabling a clear path for cables underneath and between bays.
• Is it suitable for multi-bay configurations? Yes. The design supports linking riser bases to form a continuous, organized cable path across multiple bays, improving cable management and reducing clutter during installation and maintenance.
• How do I install the RIB-1-MRK-26? Refer to the installation steps in the “How to install” section: plan layout, place and level bases, perform rough-in, and connect bases for multi-bay configurations before mounting racks and enclosures.
• Where can I find the official specifications? Official specifications are available on the manufacturer’s product listing and in the specifications section accessible via vendor channels (e.g., ec.synnex.com) using the product’s UPC or SKU as reference.
