Middle Atlantic RIB-4-MRK-26 Riser Base

Designed for professional environments where efficiency, organization, and reliable cable management matter, the Middle Atlantic RIB-4-MRK-26 Riser Base is a key component of the Raised Floor Enclosure System. This 2-1/2" high riser base is engineered to streamline field rough-in procedures, allowing installers to prepare wiring paths and outlet routes before racks and enclosures arrive on site. By elevating connections and creating a dedicated space for cables, these riser bases help you save time, reduce on-site disruption, and ensure a clean, scalable installation from day one. In multi-bay configurations, the RIB-4-MRK-26 serves as a practical lower cable chase, enabling neat cable passing between adjacent racks and preserving clear, unobstructed floor space for service access, airflow, and future expansion. Whether you’re outfitting a broadcast facility, corporate IT room, or post-production suite, this riser base delivers dependable performance, engineer-friendly design, and compatibility with Middle Atlantic’s broader ecosystem of racks, panels, and enclosure solutions.

• Time-saving field rough-in capabilities that let technicians pre-plan and route cables before racks or enclosures arrive, minimizing on-site downtime and ensuring a smoother installation workflow. The 2-1/2" riser height provides ample clearance for power, data, and signal runs while keeping cable paths organized and away from floor traffic. By enabling early rough-in, you avoid delayed projects and costly rework when equipment is delivered late or changes occur during build-out.
• Lower cable chase for multi-bay installations, giving you a dedicated channel to pass cables between adjacent racks. This design reduces cable crowding around equipment and supports clean, scalable cable management across large installations. With a centralized path for power, communications, and audio/video cabling, you gain improved cable routing discipline, easier future upgrades, and better airflow around each bay.
• Part of the Raised Floor Enclosure System, providing a cohesive, modular solution that integrates seamlessly with Middle Atlantic enclosures, accessories, and support infrastructure. The RIB-4-MRK-26 complements existing floor-base components, enabling consistent sizing, load distribution, and alignment across multiple bays. This compatibility helps maintain a professional, uniform appearance while ensuring reliable mechanical coupling and stability in active environments.
• Durable, purpose-built design that prioritizes long-term reliability in demanding settings. The riser base is engineered to withstand routine floor loading, cable movement, and the rigors of frequent reconfigurations common in media production facilities, data centers, and corporate ecosystems. By investing in a robust riser base, you protect your investment in enclosure systems and reduce the risk of misalignment or cable damage during service intervals.
• Easy integration into existing or planned infrastructure with clear sizing and straightforward layout considerations. The RIB-4-MRK-26 is sized to align with standard rack footprints and is intended to simplify the coordination between floor bases, racks, and enclosure panels. This makes it an attractive choice for facilities managers and integrators seeking a practical, scalable solution that supports future growth without requiring extensive redesign.

How to install Middle Atlantic RIB-4-MRK-26 Riser Base

• Plan your layout in advance, identifying the locations of racks, enclosures, and the desired cable routing paths. Confirm the intended multi-bay arrangement and ensure floor access points align with the riser base positions for a clean, efficient installation.
• Position each riser base at the planned locations, aligning with the interface points on the supporting floor structure or mounting framework. Ensure each unit sits level to maintain stable cable runs and to prevent misalignment during rack installation.
• Secure the riser bases according to your site’s standard mounting or anchoring practices. Use appropriate fasteners and hardware compatible with the floor surface and the weight/load requirements of the enclosure system. Tighten fasteners evenly to prevent tilt or wobble.
• Route cables through the lower cable chase as you prepare rough-in paths. Maintain separation between power and signal lines where possible and organize cables with ties or guides to preserve a clear, organized channel between bays.
• Proceed with rack and enclosure installation, then verify alignment with adjacent bays and ensure that cable paths remain unobstructed. Perform a final check for stability, slack management, and airflow considerations to confirm a professional, production-ready setup.
