Middle Atlantic WM Series 15RU Open-Frame Wall Mounted Rack - 18" Depth

The Middle Atlantic WM Series 15RU Open-Frame Wall Mounted Rack delivers a balance of robust reliability and versatile design for data centers, network closets, and professional AV installations. This 18-inch-deep wall-mount rack is engineered to maximize available space without sacrificing capacity or accessibility, making it an ideal choice for environments that demand clean cable management, strategic airflow, and ready access to critical equipment. Built around a self-squaring, open-frame concept, the WM Series accelerates installation and simplifies ongoing maintenance, so technicians can quickly mount, reconfigure, or expand their infrastructure as needs evolve. Whether you are housing fiber-optic equipment, enterprise switches, patch panels, or mixed 19-inch gear, this rack provides a stable, trusted foundation that keeps your system organized and performing at peak levels.

• Self-squaring, open-frame design facilitates quick, level installation and effortless maintenance. The precision-aligned frame ensures components sit true to plumb, while the open-frame construction promotes unrestricted airflow and simplifies cable routing behind and around the rack. This design translates to faster deployments and easier future upgrades in crowded IT rooms or AV environments.
• Fixed frame protects fiber optics during installation The rigid, non-flexing frame minimizes bending and potential kinking of glass fibers as cabling is pulled and organized. This preservation of fiber integrity helps maintain signal quality and reliability, a critical factor in modern telecom and data networks where even small perturbations can impact performance.
• 15U capacity with 18" depth for broad compatibility The combination of 15 rack units and an 18-inch depth accommodates a wide range of 19-inch equipment—from passive patch panels and switches to fiber adapters and line cards—while remaining compact enough to fit in tight wall spaces. This capacity enables scalable deployments without the need for multiple enclosures or adapters, simplifying inventory and cabling strategies.
• Rugged steel construction for long-term durability Built to withstand the demands of commercial environments, the WM Series rack features sturdy steel fabrication designed to endure routine equipment changes, cable maneuvers, and the vibrations common in data centers and service rooms. A durable finish protects against corrosion and daily wear, helping preserve the rack’s alignment and appearance over years of use.
• Versatile mounting for data, telecom, and fiber applications This open-frame wall rack is suitable for a broad spectrum of installations, including data centers, network closets, telecommunications rooms, and audiovisual setups. Its wall-mount design saves floor space while delivering reliable mounting for critical equipment, organized cabling, and efficient cooling, making it a dependable backbone for growing IT infrastructures.

how to install Middle Atlantic WM Series 15RU Open-Frame Wall Mounted Rack

• Choose a suitable wall location with solid structural support and ensure there is adequate space for front access, rear cabling, and ventilation. Verify that the wall can bear the combined weight of the rack and all mounted equipment.
• Position the rack against the wall and use a level to confirm it is plumb and square. This careful alignment is essential to maximize airflow, ensure proper operation of mounted equipment, and prevent strain on cables.
• Assemble the open-frame components if needed, aligning sections to achieve a true square frame before securing. The self-squaring design simplifies this step, reducing the chance of misalignment during setup.
• Secure the rack to the wall using appropriate hardware rated for your wall type (studs, concrete, or other structural substrate). Tighten fasteners evenly to maintain level alignment and stability under load.
• Install your 19-inch equipment rails or compatible mounting hardware, then mount devices in accordance with their weight and space requirements. Route power and data cables neatly, using cable management provisions and tie-downs to preserve airflow and accessibility for maintenance or future changes.
• Perform a final check to ensure all devices are firmly seated, cables are organized, and there is no strain on connectors. Power up the system and verify that airflow is unobstructed and that equipment operates within expected thermal margins.
