The Middle Atlantic MS-5.5-4 rack mounted shelf is a thoughtfully engineered solution for organizing and securing small components within a 19" rack. With a compact 5.5-inch depth and a 1/2 rack unit footprint per shelf, this four-pack delivers flexible placement options for front- or rear-access devices without sacrificing valuable rack space. It’s ideal for housing small routers, patch panels, compact power strips, network gear, media players, or accessories that need quick access and tidy, dependable cable management in busy AV, broadcast, or IT environments. The shelf’s thoughtful hole and slot pattern accommodates a wide variety of mounting hole configurations, making it a versatile choice for upgrading an existing rack or building a compact, scalable rack system from the ground up. In short, Middle Atlantic has designed this shelf to simplify deployment, improve ergonomics, and maintain a clean, professional rack appearance where cable management matters just as much as device placement.

• Front or rear mounting flexibility: The MS-5.5-4 shelf supports convenient placement at either the front or rear of your rack, letting you tailor your layout to your workflow, cabling strategy, and access preferences. The versatile hole pattern accepts a broad range of mounting configurations so you can adapt as your equipment changes.
• Four-shelf pack for scalable organization: This is a four-pack, giving you multiple mounting points to consolidate small gear across the rack while preserving space for future growth. Each shelf maintains a compact 5.5" depth, maximizing usable rack area for other equipment and ensuring easy reach to connected cables.
• Durable steel construction with powder coat finish: Built to withstand demanding environments, the shelves use sturdy steel and a protective powder-coated finish to resist wear, scratches, and corrosion. The durable surface keeps gear looking professional even after years of use, installation, and reconfiguration.
• Enhanced cable management and tie-down points: In addition to the broad mounting pattern, the MS-5.5-4 provides ample tie-down points and intentional cable routing paths. This helps you secure power and data cables, maintain clean cable runs, and reduce movement that can lead to wear or downtime during equipment changes.
• Standard 19" rack compatibility with simple integration: Designed to work with standard 19" racks and common mounting hardware, the Middle Atlantic shelf integrates smoothly with your existing system. It’s an unobtrusive, highly adaptable accessory that complements other Middle Atlantic products and accessories for a cohesive, professional rack setup.

• Position the shelf at the desired height and align the mounting holes with the rack rails; insert and tighten the screws or fasteners at all four corners to secure the shelf firmly to the rack.
• Place your small devices onto the shelf, ensuring there is adequate clearance for cables and ventilation. Route cables through the shelf’s holes and slots, using the built-in tie-down points to secure cables and prevent movement during operation or servicing.
