Middle Atlantic Riser Base, 4 Bay, 27"D for BGR Racks

Streamlined and reliable, this 4-bay, 27" deep riser base from Middle Atlantic delivers a time-saving solution for rough-in rack installations. Built to withstand demanding professional environments, the base raises equipment by 2-1/2 inches, provides beneath-space cable routing, and aligns perfectly with BGR rack configurations. With a heavy-duty welded construction and a durable black powder coat finish, it remains sturdy under load while maintaining a clean, professional appearance. Whether you’re wiring a data-center rack build, a sophisticated AV installation, or an enterprise-grade network rack, this riser base simplifies installation, speeds up turnaround, and enhances cable management for years of dependable service.

• The riser base is engineered to accelerate rough-in work, offering a timesaving, practical system that keeps cables organized and out of sight. Its design reduces the number of field adjustments needed during installation, allowing technicians to complete builds faster while maintaining professional cable routing. This is especially valuable in dense installations where time-to-turn-up matters, and every minute saved translates into lower labor costs and tighter project schedules. With the 2-1/2" base height, you'll gain essential space for connectors, patch cords, and under-base routing without sacrificing clearance for air flow or service access.
• Durable, heavy-duty welded construction ensures long-term reliability in rack environments that see frequent use and movement. The welded steel framework provides superior strength compared to hollow or riveted alternatives, resisting bending, flexing, or fatigue under load. The black powder coat finish adds a robust layer of protection against abrasion, scratches, and environmental exposure, keeping the base looking professional even after years of installation, reconfigurations, and equipment swaps. This combination of rugged construction and attractive finish makes the riser base a core component of any high-demand rack system.
• Precise compatibility with 4-bay BGR racks and standard rack footprints ensures a seamless fit. The base is designed to match the width and mounting patterns of 4-bay configurations, allowing cables to pass underneath the rack as needed for clean, unobtrusive cabling. By coupling the riser base with compatible rack systems, you can maintain consistent alignment across multiple cabinets and achieve a unified, factory-polished appearance. The 27" depth is chosen to accommodate common deep equipment and patches while preserving adequate clearance for rear cabling and airflow management.
• Enhanced cable management is built into the base’s concept. The underside cable-pass design minimizes clutter on the floor and reduces trip hazards while enabling easier service access for rear connections. By elevating the rack and creating space beneath, technicians can route power cords, data cables, and audio/video lines through unobstructed paths, lowering the risk of tangling and interference. This organized approach improves signal integrity and reduces the likelihood of accidental disconnections during equipment changes or upgrades.
• Easy integration and scalable setup make this riser base an essential component for professional systems. The 2-1/2" height offers optimal clearance for ventilation and heat dissipation, while the sturdy base provides stable support for equipment loads typical of server, AV, and communications racks. The combination of practical design, solid construction, and a clean, black finish ensures the base not only performs well but also complements the aesthetics of high-end rack installations. As part of the Middle Atlantic family, the riser base benefits from reliable engineering and a track record of dependable performance in mission-critical environments.

How to Install Middle Atlantic Riser Base, 4 Bay, 27"D

• Prepare your installation area by ensuring a level, clean surface where the rack will be positioned. Check for existing floor obstructions and verify that the mounting footprint aligns with the base and rack’s standards.
• Place the riser base under or adjacent to the rack frame as appropriate for your model, making sure the 4-bay alignment matches the rack’s mounting pattern. Align the base with the rack to ensure even weight distribution and proper clearance for cables beneath.
• Secure the base to the rack or floor using the manufacturer’s recommended hardware and mounting points. Tighten fasteners evenly to avoid creating stress points on the welded frame and to maintain level alignment across the system.
• Route cables beneath the base as required. Take advantage of the under-base space to organize power and data cords, labeling runs for easy future maintenance. Ensure cables do not crimp or bind when the rack is loaded with equipment and that vent areas remain unobstructed for effective cooling.
• Install the rack assembly onto the base, verify proper alignment, and perform a final cable management check. Confirm that all connections are secure, airflow is unobstructed, and doors or panels on the rack clear the base without interference. Perform a quick functional test to ensure that equipment powers on and connectivity remains intact after the installation.
