Middle Atlantic Custom Wide Shelf, 4 RU, 17.5"D, Anodized

The Middle Atlantic Custom Wide Shelf is a purpose-built solution for engineers, audio-visual technicians, and IT professionals who demand a precise, professional fit inside standard 19" enclosures. Built around the proven RSH custom rackmount concept, this 4‑RU shelf lets you install virtually any component without cutting or modifying the enclosure. The shelf is custom-cut to provide a perfect opening that matches the front face of the mounted equipment, delivering a neatly trimmed installation with a clean, showroom-ready appearance. Its anodized finish adds an extra layer of durability, resisting wear in demanding environments while maintaining a sleek, low-profile look that blends seamlessly with other middle Atlantic gear. Whether you’re outfitting a broadcast studio, control room, data center, or home theater rack, this shelf is designed to maximize space, minimize drama, and improve overall system reliability.

• Custom-fit design with RSH rackmounts: Engineered for precision, the RSH system creates a tailored opening that mirrors the component’s face. No modification is required to the enclosure, reducing installation time and eliminating the risk of misalignment or panel gaps. The result is a professional, flush installation that looks as good as it performs.
• Extended depth for versatile component accommodation: With a depth of 17.5 inches, this shelf accommodates a wide range of 19" equipment, from power distributors and multi-IO interfaces to large audio/video modules and bulky peripherals. The generous depth also leaves room for rear cabling, ensuring you can route power and data lines cleanly without crowding the front panel.
• Durable anodized aluminum construction: The anodized finish provides superior corrosion resistance and enduring aesthetics in challenging environments. Lightweight yet strong, the material stands up to frequent rack access, cable movements, and the occasional rack-mount reconfiguration, all while maintaining its sleek, professional look over time.
• Optimized 4U height for efficient space use: Four rack units (4U) tall translates to a compact footprint that still accommodates a substantial front-facing installation. This height is ideal for mid-sized components, ensuring you maximize rack real estate while preserving ample space for airflow and straightforward maintenance access.
• Universal compatibility with standard 19" racks: Built to align with standard 19" enclosures, this shelf integrates smoothly with a wide array of equipment, accessories, and configurations. Its precise dimensions and mounting tolerance make it a versatile choice for mixed-brand racks, enabling a cohesive, modular approach to system design.
