Middle Atlantic SNE Series Rack, SNE27H-4542-A2

The SNE27H-4542-A2 rack from Middle Atlantic’s SNE Series is engineered for hybrid security systems that blend analog and digital equipment into a single, secure enclosure. It delivers a reliable home for encoders, power supplies, access control devices, and other compact components while preserving space, airflow, and organization in demanding installation environments. At the heart of its design is the patented Zero-U Tool-Free Lever Lock system, which lets technicians mount and secure devices without occupying front U-space, reducing setup time and minimizing tool requirements. A fully configured Security Net protects internal cabling from accidental disconnection or interference, while cable management pathways and robust construction ensure long-term performance in data centers, security rooms, and network operations centers. For integrators and installers, the SNE27H-4542-A2 combines flexibility, durability, and scalability to support evolving hybrid networks with ease, making it a smart choice for projects that require clean aesthetics, rapid deployment, and dependable operation.

• Hybrid security design for mixed analog and digital gear: The SNE27H-4542-A2 is purpose-built to accommodate small devices such as encoders, power supplies, and access control systems, all within a compact 27U-high, 19-inch-wide enclosure. The internal layout supports secure mounting, efficient cable routing, and scalable growth as your network expands, including room for additional devices or accessories without disassembly. This approach reduces rack clutter, enables centralized management, and simplifies future upgrades as your security and AV needs evolve.
• Zero-U Tool-Free Lever Lock system: This patented mechanism lets you secure new devices at the front of the rack while keeping the front U-space free for clean, unobstructed equipment installation. The lever-lock rails adjust quickly to different device depths, enabling rapid deployment and maintenance without tools, reducing downtime and service calls in mission-critical environments. By eliminating the need to crowd front rail space, installers can prioritize cable management and airflow, contributing to more reliable device performance over time.
• Fully configured Security Net and cable management: The Security Net creates a protective barrier around installed devices, preventing accidental unplugging during service and improving cable routing. It also helps with airflow and reduces the risk of cable damage or snagging during maintenance. The net is designed for easy removal when service is required, so technicians can access components without unmounting other gear. Coupled with dedicated cable channels and tie-down points, this system keeps installations neat, compliant with professional standards, and easier to service after deployment.
• Durable, standard 19-inch rack footprint with expansion-ready architecture: The SNE27H-4542-A2 uses a rugged, heavy-gauge steel chassis with a durable powder-coated finish engineered for long service life in challenging environments. It conforms to standard 19-inch rack dimensions, ensuring compatibility with a broad ecosystem of accessories, mounting rails, and fittings from Middle Atlantic and third-party partners. The robust construction supports consistent performance in temperature-controlled rooms, equipment closets, and service corridors, while its design prioritizes ease of access for maintenance and upgrades.
• Optimized for hybrid security deployments with scalable cabling: Beyond holding encoders and power bricks, the rack supports various security subsystems such as access control panels, door controllers, and network devices. Its intelligent internal layout and cable management features minimize heat buildup and maximize airflow, helping maintain device performance in temperature-controlled rooms or closet installations. This flexibility makes the SNE27H-4542-A2 suitable for evolving hybrid configurations, where new components can be added with minimal rework.
