Middle Atlantic Custom Wide Shelf, 3 RU, 11.5"D, Textured

The Middle Atlantic Custom Wide Shelf is engineered for professional racks where a clean, reliable mounting solution matters as much as the gear you place on it. Designed to fit standard 19" enclosures, this shelf delivers a precise, secure opening for your equipment while maintaining a sleek, low-profile appearance. With its textured finish and rugged steel construction, it stands up to busy AV rooms, studios, and racks that see frequent use. Whether you’re housing routers, servers, patch panels, or compact AV components, this shelf provides a dependable foundation that keeps gear organized, accessible, and neatly contained.

• Precise, modification-free fit in standard 19" racks. The Custom Wide Shelf is cut to align perfectly with the face of the component being mounted, so you get a neat, professional installation without needing to drill or alter your enclosure. This thoughtful design minimizes gaps, reduces equipment movement, and preserves the rack's clean, symmetrical appearance even in tight spaces.
• 3 RU height (5.25 inches) for versatile component placement. With 3 rack units of vertical space, you can stack multiple devices or accommodate a mid-sized piece of gear on a single stable surface. The extra headroom helps with airflow and cable management, making it easier to remove, upgrade, or service equipment without disturbing adjacent gear.
• 11.5" depth to accommodate a wide range of gear and cables. The shelf’s depth is ideal for mid-depth components and ensures ample room behind the front face for tidy cabling, power strips, and rear connectors. This generous depth encourages proper ventilation, reduces heat buildup, and gives you room to route cables without cramping the equipment on the shelf.
• Durable textured finish for longevity and professional aesthetics. The textured powder-coated surface resists scratches, scuffs, and fingerprints, maintaining a polished look even in high-traffic racks. The finish not only enhances durability but also helps to disguise minor imperfections that can occur with heavy daily use, preserving a consistent, professional appearance over time.
• Rugged, all-steel construction designed for demanding environments. Built to withstand the daily rigors of broadcast rooms, recording studios, data centers, and installation sites, this shelf provides a solid foundation for valuable equipment. The robust construction supports reliable mounting, reduces flex, and contributes to the overall integrity of the rack system as components are swapped, upgraded, or reconfigured.

• Slide the Custom Wide Shelf into the rack rails at the chosen location, aligning the front face with the rack’s front panel for a clean, flush appearance.
• Secure the shelf to the rack using standard rack screws into the mounting ears or threaded holes on the rails. Tighten evenly to prevent any tilt or wobble.
• Place your equipment onto the shelf, distributing weight evenly to maintain stability and airflow. If you’re mounting multiple devices, consider weight balance and cable routing behind the front face.
• Route cables and power connections with care, using cable ties or organizers to keep the area tidy and to maximize ventilation. Recheck screw tightness after setup and perform a light test to ensure everything remains secure during operation.

Frequently asked questions

• What does 3 RU mean in practical terms? 3 RU refers to the vertical space the shelf occupies in a standard 19" rack, equivalent to approximately 5.25 inches of rack height. This allows for mounting multiple devices or a single, mid-sized component with space for airflow and cable management.
• Will this shelf fit all 19" racks? Yes. It is designed to fit standard 19" rack enclosures and pairs with typical rack rails. Always confirm your rack’s internal mounting dimensions and ensure there is adequate depth for your specific equipment plus cabling.
• What materials and finish are used? The shelf is built from heavy-duty steel and finished with a textured powder coating. This combination provides durability, scratch resistance, and a professional look suitable for high-use environments.
• Are mounting screws or hardware included? Hardware requirements can vary by vendor and model. In most cases, standard rack screws and mounting hardware are used, but you should verify whether screws/rails are included with your purchase to avoid needing a separate order.
• Can I mount heavy equipment on this shelf? The shelf is designed for standard rack use and general equipment placement. For maximum safety, distribute weight evenly and consider the device’s weight rating in relation to your rack’s overall load capacity. If you have unusually heavy gear, consult the manufacturer’s specifications or support resources for weight limits and recommended configurations.
