Middle Atlantic Custom Wide Shelf, 4 RU, 14"D, Anodized

Engineered for precision and versatility in professional racks, the Middle Atlantic Custom Wide Shelf offers a superior mounting solution for a wide range of 19" enclosure components. Built on the renowned RSH platform, this shelf is custom-cut to create a perfect opening for the component face, delivering a clean, professional installation with no unnecessary gaps or awkward blemishes. The anodized finish not only provides a sleek, durable appearance but also adds corrosion resistance for demanding environments such as broadcast studios, control rooms, data centers, and live event setups. With 4 RU of vertical space and a generous 14" depth, you gain the balance of ample room for deeper modules, ventilation considerations, and cable management, while maintaining a slim profile that respects rack real estate and airflow. This shelf is designed to integrate seamlessly into standard 19" racks, ensuring compatibility with existing rails, brackets, and accessories in a way that preserves the integrity of your rack system and your components.

Whether you’re outfitting a new rack build or upgrading an aging install, the Custom Wide Shelf from Middle Atlantic delivers a practical, high-performance solution that reduces installation time and improves the overall finished appearance of your rack. The 4 RU height is ideal for mounting mid-size power supplies, signal processors, compact converters, or modular units, while the 14" depth accommodates larger front panels and deeper heat-generating hardware. The RSH philosophy centers on creating a dedicated mounting opening for each component, which minimizes front-face play and helps to maintain a consistent, professional look across the entire rack. The result is a sturdy, vibration-resistant platform that keeps sensitive electronics properly supported and aligned—key for reliable performance in busy control rooms and portable production environments alike.

• Precise front-face opening: The custom-cut opening matches the component’s faceplate, delivering a snug, professional fit that reduces rack gaps and improves thermal and cable management while maintaining a visually clean presentation.
• Generous 14" depth: Designed to accommodate deeper power supplies, fans, and modular assemblies without crowding the front panel or obstructing airflow, enabling better cooling and longer component life.
• Rugged anodized construction: Anodized aluminum resists wear, scuffs, and corrosion in demanding environments, ensuring the shelf stays looking sharp and performing reliably over time.
• 19" rack compatibility: Engineered to fit standard 19" enclosures and rails, making it straightforward to integrate into existing systems with minimal modification or extra hardware.
• Effortless integration and serviceability: The shelf is designed for quick installation and easy component swaps, enabling faster maintenance, upgrades, and reconfigurations without compromising stability or alignment.

How to install Middle Atlantic Custom Wide Shelf

• Plan your rack layout by identifying the desired location for the component with the 4 RU footprint. Confirm that there is adequate clearance for both the depth (14") and any cooling airflow paths around the front and rear of the rack.
• Prepare the rack by inspecting rails and mounting hardware. If necessary, remove a blank panel and ensure rails are clean, aligned, and capable of supporting the shelf’s weight and the mounted component.
• Insert the Custom Wide Shelf into the rack, aligning the custom cut face opening with the front face of the target component. Slide the shelf until it sits flush against the rack rails and the front bezel aligns with the overall rack front.
• Secure the shelf using the standard rack mounting hardware appropriate for your enclosure. Verify that the shelf is level and firmly fastened to the rails to prevent vibration or movement during operation.
• Install the component into the shelf’s opening, or place the component onto the shelf if it is a non-drawer style. Align the component’s front panel with the rack front, attach any necessary brackets or screws, and connect cables. Do a final inspection to ensure proper clearance, cable routing, and unobstructed airflow before powering on.
