The Middle Atlantic RL 10-38 is a heavy-duty, open-frame rack designed for commercial and industrial equipment installations where maximum accessibility, ventilation, and integration flexibility are required. As part of the RL (Rack-Like) Series, it provides the structural support and standardized mounting capabilities of a traditional 19-inch equipment rack without the side panels or rear door, offering unimpeded access to all sides of installed gear for cabling, maintenance, and heat dissipation. The rack's defining dimensions are a 15.25-inch depth (inside width between the mounting rails) and a 72-inch overall height, providing substantial vertical space—equivalent to approximately 42 rack units (RU)—to house large quantities of servers, networking hardware, broadcast equipment, or power distribution systems in a single, organized structure.

Constructed from durable, cold-rolled steel with a black powder-coat finish, the frame is engineered for stability and strength, capable of supporting significant distributed weight loads. The unit features four fully adjustable, industry-standard 19-inch EIA mounting rails, with square-hole threading that allows for precise positioning of equipment at any point. The rails are typically numbered for easy RU measurement, and the rack includes leveling feet to ensure stability on uneven floors. Its open-frame design makes it an ideal choice for data centers, network closets, equipment rooms, and technical cores where equipment needs to be frequently serviced, where cable management must be meticulously organized on all sides, or where heat-generating devices require optimal airflow that would be restricted by a closed cabinet.

This rack serves as a foundational infrastructure component, designed to be integrated into larger systems or used as a standalone unit. Its versatile, no-frills design allows for customization with a wide range of Middle Atlantic accessories, such as cable management arms, vertical wire managers, shelves, and fan panels. By providing a robust, standardized, and accessible framework, the RL 10-38 facilitates a clean, professional, and serviceable installation, ensuring that valuable electronic equipment is securely housed, properly cooled, and efficiently organized for long-term reliability and ease of operation.
