Middle Atlantic Custom Wide Shelf, 4 RU, 20.5"D, Textured

Designed for professional AV, IT, and broadcast environments, the Middle Atlantic Custom Wide Shelf delivers a robust, space-efficient solution for organizing gear inside standard 19" racks. At 4U high and 20.5" deep, this shelf accommodates deep components, patch panels, or custom modules that require a precise face opening. The textured finish resists scuffs and fingerprints in busy rack rooms, while the RSH-enabled design ensures a clean, flush fit for devices with non-standard bezels. Whether upgrading an editing suite, control room, or data closet, this shelf balances durability, accessibility, and professional presentation in a single, easy-to-install package.

• Custom fit with RSH mounting: The shelf is cut to provide a perfect opening for the face of the mounted component, delivering a neatly trimmed, flush installation inside a standard 19" enclosure. This avoids protruding lips and awkward gaps, making the equipment look built-in and performing at its best.
• 4U height for flexible equipment packing: With 4 rack units (4U) of vertical space, you can stack multiple devices or accommodate deeper modules while maintaining clear front access for cables, LEDs, and controls. The 4U form factor is ideal for mid-sized AV racks and compact data centers.
• 20.5" depth for deep gear: The extended depth (20.5 inches) supports a broad range of components, from large power supplies and multi-slot adapters to custom-face devices. This generous depth helps with hardware compatibility and cable management behind the panel.
• Durable textured finish: Built for regular rack room use, the shelf features a textured powder-coated finish that resists scratches, scuffs, and fingerprints. The rugged surface preserves appearance over time in high-traffic environments and simplifies maintenance.
• 19" rack compatibility and modern integration: Engineered to fit standard 19" racks, this shelf works with common rack rails and mounting hardware. The combination of a sturdy steel build and precise cutouts ensures a clean installation that integrates with other Middle Atlantic components and a wide ecosystem of rack accessories.

How to install Middle Atlantic Custom Wide Shelf

• Plan placement in the rack: Determine the optimal 4U position based on the weight distribution, accessibility, and front-panel visibility. Heaviest items should be placed lower to ensure stability and ease of service.
• Prepare mounting hardware: Gather the appropriate rack screws and mounting hardware compatible with your 19" rack rails. If your rack uses a rear-mamping or seismic kit, ensure compatibility with the shelf’s mounting points.
• Position the shelf: With the rack rails aligned, slide the Custom Wide Shelf into the rack at the chosen 4U location. Ensure the front face and mounting holes align with the rack’s front rails for secure fastening.
• Secure the shelf: Use the recommended rack screws to fasten the shelf to the front rails. Tighten evenly to avoid misalignment and to maintain a flush, professional appearance with the component’s face opening.
• Install the component and align the face opening: Place the device that requires the custom face opening into the shelf. Use the RSH cutout to align the component’s face with the opening, ensuring a precise, flush presentation. If needed, attach any brackets or supports per your rack configuration.
• Cable management and final checks: Route power and signal cables behind the shelf, taking care to maintain airflow and avoid pinching. Verify that all connectors are accessible from the front, and confirm there are no interference issues with neighboring equipment.
