Middle Atlantic Riser Base, 3 Bay, 27"D, BGR Racks

Designed for fast, reliable rough-in rack installations, the Middle Atlantic Riser Base 3 Bay offers a stable, scalable platform that aligns with standard 19" rack widths. With a generous 27" depth and a 2-1/2" high base, it creates clean, accessible space underneath the rack for cabling, power distribution, and airflow management. Built for professional environments, this heavy-duty welded base features a durable black powder coat finish that resists wear and looks polished in any rack room. Whether you’re provisioning new installations or retrofitting existing systems, this riser base speeds up setup, reduces on-site fabrication, and helps you maintain organized, safer cable routing across multiple racks.

• 3-Bay, 27" depth design: The riser base provides a stable, uniform platform that aligns with standard 19" equipment and supports multi-unit configurations. The 2-1/2" high base creates a dedicated under-rack space perfect for cables, power strips, and interconnects, all while preserving essential mounting clearance. Built with heavy-duty welded construction, it delivers enduring strength to support mounted gear and the rigors of busy data rooms or broadcast facilities. This design enables quick, repeatable rough-in installations without compromising alignment or rigidity across crews and projects.
• Cable management underneath for cleaner installs: The elevated base forms a defined channel beneath the rack, allowing power and data cables to run out of sight and out of the way. This not only reduces clutter on the front of the rack but also enhances airflow, lowers heat buildup, and minimizes stress on connectors by keeping cables routed in a predictable, organized path. It’s an ideal solution for AV, IT, and control room applications where neat cabling impacts reliability and serviceability.
• Durable finish for demanding environments: Coated in a black powder finish, the riser base resists scratches, scuffs, and corrosion—maintaining a professional look in high-traffic rooms and environments prone to wear. The rugged coating pairs with the welded steel construction to withstand repeated assembly, disassembly, and reconfigurations common in installations that evolve with technology needs.
• Compatibility and versatile applications: Specifically designed for Middle Atlantic BGR Racks and standard 19" equipment, this 3-bay riser base supports flexible configurations from initial rough-ins to later expansions. It’s well-suited for audio-visual systems, data centers, broadcast suites, educational campuses, and industrial control rooms where dependable rack foundations and tidy cable routing matter most. The modular nature of the base makes it easy to integrate with other Middle Atlantic components for cohesive, scalable systems.
• Time-saving, reliable performance: By eliminating the need for in-field fabrication and custom cutouts, this riser base accelerates project timelines and reduces labor costs. The precise, pre-engineered design ensures consistent mounting alignment across racks, improves project predictability, and minimizes on-site adjustments. This translates to faster deployments, quicker serviceability, and a neater overall installation that stands up to daily use.
