Middle Atlantic Custom Wide Shelf, 6 RU, 20.5"D, Textured

Engineered for professional AV and IT installations, the Middle Atlantic Custom Wide Shelf (RSH) is the smartest way to add depth and versatility to any standard 19" enclosure. With a precisely cut face opening, it is constructed to work with Middle Atlantic's RSH custom rackmounts for a flawless, professional appearance. The shelf is 6 RU tall and 20.5 inches deep, providing ample space for a broad range of components—from compact audio/video processors and power supplies to compact servers and network gear. The textured finish protects the shelf from scuffs and wear, and coordinates with other Middle Atlantic enclosures for a cohesive rack system. The RSH system is celebrated for its modular approach: you can install components without modifying the enclosure, then swap or upgrade gear as needs evolve. This shelf is not only about support; it's about optimizing your rack for cleanliness, airflow, and efficiency. The precisely cut opening ensures the front panel of the mounted device sits flush with the rack frame, delivering a neat and professional look that’s crucial in broadcast and performance environments where sightlines and accessibility matter. Because the shelf integrates into standard 19" equipment racks, technicians can quickly deploy or reconfigure gear without custom fabrication or downtime. The 6 RU footprint makes it especially suitable for mid-sized installations where you need to balance height with depth to accommodate deep cabinets, power distribution units (PDUs), or large I/O cards, while maintaining sufficient rear clearance for cabling and thermal management. In short, the Middle Atlantic Custom Wide Shelf provides a robust, modular mounting platform that protects devices, simplifies installation, and preserves the visual integrity of your rack. This is a practical choice for studios, post-production facilities, enterprise AV setups, and high-demand data centers where reliable rack solutions matter as much as the gear itself. Built to endure through daily use, the textured finish withstands knocks, scuffs, and the rigors of frequent reconfiguration, helping you preserve an orderly, professional rack even as you upgrade equipment. When combined with the RSH custom rackmounts, it offers a streamlined, tool-free way to expand or reconfigure your rack space while keeping cables organized and accessible for routine maintenance and service. If you’re upgrading a rack or building a new installation, this shelf ensures you get a precise, flush face alignment, maximizing the effective mounting area of your 19" enclosure without compromising accessibility or cooling.

• Custom cut opening ensures a precise fit for the face of the mounted component, delivering a clean, professional appearance and eliminating gaps that can collect dust or disrupt airflow. The open face aligns exactly with the rack frame, reducing installation time and the need for trimming or modification.
• Designed for standard 19" enclosures without modification, the shelf integrates seamlessly with existing racks and RSH components, enabling quick retrofits, upgrades, and scalable deployments across home theaters, broadcast studios, and IT closets.
• Six RU height and 20.5" depth provide generous space for a wide range of equipment—ranging from audio processors and video switchers to compact servers or PDUs—while preserving rear clearance for cabling, power management, and ventilation to maintain performance.
• Durable textured steel finish resists everyday wear, scratches, and fingerprints, maintaining a professional rack aesthetic over time and matching other Middle Atlantic enclosures and hardware for a cohesive look.
• Sturdy mounting surface and robust construction support heavier gear with stable alignment in the rack, reducing rack bounce during transport and ensuring devices stay in place during routine maintenance, upgrades, or reconfigurations.
