Middle Atlantic Custom Shelf, 7 RU, 17.5"D, Anodized

Engineered for professional AV, IT, and broadcast rack environments, the Middle Atlantic Custom Shelf is a purpose-built 7 RU, 17.5" deep shelf designed to maximize space and deliver a precise, professional fit inside any standard 19" enclosure. This shelf is part of Middle Atlantic's RSH family of custom rackmounts, a solution that allows virtually any component to be mounted in a standard 19" enclosure without modification. By providing a custom-cut opening tailored to the exact face of the equipment, the RSH system ensures a neat, integrated appearance with a clean edge line and minimized gaps. The anodized finish adds durability and resistance to wear, making it suitable for demanding installations—from studio racks and touring systems to data centers and high-traffic comms rooms. Whether you’re upgrading an existing rack or building a modular backbone for a growing system, this shelf combines precision, resilience, and ease of installation to deliver a dependable, professional result every time.

• Custom-fit face opening with RSH — The innovative RSH rackmounts are machined to match the exact silhouette of the component you’re mounting, creating a neatly trimmed face opening that looks built-in rather than ad hoc. This precise fit reduces movement, protects front panels from accidental contact, and preserves easy access to front-mounted controls, LEDs, and connectors. The result is a clean, professional installation that reduces installation time and minimizes the need for adapters or additional shims. In addition, the snug fit supports better airflow management by minimizing unnecessary gaps around the device, contributing to cooler operation in crowded racks.
• Standard 19" rack compatibility — Designed to drop into any standard 19" equipment rack or enclosure, this shelf makes it simple to reconfigure or expand your rack without fabricating new mounting solutions. The 7 RU height is ideal for a broad range of equipment, from compact network switches and patch panels to compact processors, power distribution units, and small audio/video modules. The result is a modular, scalable rack configuration that maintains a consistent aesthetic and functional layout across all devices, with the shelf acting as a stable foundation for future upgrades.
• Generous depth for cable management — With a 17.5" depth, the shelf provides ample room behind the front face for cabling, connectors, and ventilation. This depth supports organized cable runs, reduces stress on front-panel interfaces, and improves airflow—key factors in maintaining equipment longevity in dense rack environments. The extra clearance also makes it easier to route power, data, and I/O cables without crimping or bending, which helps prevent intermittent connections and supports reliable long-term operation in broadcast studios, control rooms, and IT suites.
• Durable anodized aluminum finish — The anodized aluminum construction delivers rugged durability and corrosion resistance, maintaining a sleek, professional appearance even with frequent rack access and transport. The finish resists fingerprints and wear, reducing the need for frequent touch-ups and cleaning in busy facilities. An anodized shelf maintains its metallic luster and smooth operation across a wide range of environments, from climate-controlled studios to equipment closets with variable humidity and temperature fluctuations.
• Versatile, upgrade-ready shelf — This shelf is designed to accommodate evolving rack layouts. The combination of a precise, custom-fit opening, robust materials, and standard 19" compatibility makes it a reliable building block for expanding systems. When you add new gear or swap components, the shelf remains a stable, secure platform, minimizing the need to reconfigure rails or other rack elements. It’s an excellent choice for both new installs and ongoing upgrades, ensuring consistent performance and a cohesive, professional look as your rack grows.

How to install Middle Atlantic Custom Shelf, 7 RU, 17.5"D, Anodized

• Prepare the rack and equipment: Power down all devices and ensure the rack area is clean and free of obstructions. Verify that the enclosure rails are level and secure, and confirm the rack’s depth is compatible with a 17.5" shelf. Clear the front of the rack to allow full access to the mounting rails and faceplate space for the component you plan to install.
• Identify the mounting location: Locate the designated 19" mounting region that corresponds to the 7U height. Check for any existing components or rails that might affect clearance or alignment, and plan cabling routes before inserting the shelf.
• Prepare the RSH opening: If your component requires a custom face opening, verify that the RSH cutout matches the component’s front profile. Align the shelf so that the intended front face will align cleanly with the enclosure’s face, ensuring a tidy installation with no protruding edges or gaps.
• Install the shelf into the rack: Slide the shelf into the rack rails, ensuring the 19" mounting holes line up properly. Secure the shelf using the enclosure’s standard hardware or the hardware provided with the shelf, tightening evenly to prevent any bowing or misalignment. Confirm the shelf sits flat and square within the rails for stable support of attached equipment.
• Mount equipment and finalize cabling: Place your component onto the shelf, align with the RSH opening, and secure it if required by the design. Connect power, data, and I/O cabling, then manage cables using ties or Velcro to maintain airflow and access to front controls. Test power and signal paths to verify proper operation and ensure that the installation remains easy to service in the future.
• Inspect and document: Perform a final inspection for front-face alignment, cable routing, and cable slack. Label cables if needed for future maintenance and update rack diagrams to reflect the new shelf and component configuration. A well-documented, tidy rack reduces maintenance time and helps keep equipment running smoothly over long operational lifespans.

Frequently asked questions
