Middle Atlantic 40 RU WRK-SA Series 24-1/4 Inch Wide Rack, 32 Inches Deep without Rear Door

The WRK-SA series from Middle Atlantic is built to handle the demands of modern equipment racks where a wider footprint and deeper mounting depth make a real difference. Engineered with stand-alone installation in mind, this 40U rack delivers a robust, fully welded chassis with fixed solid sides and seismic certification to meet the needs of mission-critical installations. Designed to accommodate thicker cable bundles and promote superior cooling airflow, the WRK-SA 24-1/4 inch wide rack is a versatile foundation for data centers, AV facilities, telecom rooms, and industrial environments where reliability, accessibility, and long-term performance matter. The combination of a generous 40‑U capacity, a generous 24-1/4 inch width, and a 32 inch depth creates ample room for dense equipment, deep frame devices, and substantial cable slack, enabling clean, organized installations that are easy to service and expand over time.

• Designed for thicker cable bundles and improved cooling: The wider footprint and deep mounting space reduce congestion, improve airflow, and make cable management simpler, helping to maintain consistent temperatures across dense equipment layouts.
• 40U rack capacity for scalable installs: With 40 rack units of mounting space, you can consolidate servers, network switches, patch panels, UPSs, PDUs, audio/visual gear, and other critical equipment into a single, organized enclosure.
• Stand-alone installation with fixed solid sides: The WRK-SA model is built as a self-contained unit, offering rigidity and protection without the need for a rear door. Fixed sides provide excellent chassis stiffness and reliable separation of front-facing equipment from the environment.
• Fully welded, durable construction: The complete welded construction delivers superior strength and long-term rigidity, reducing potential misalignment and ensuring stable equipment mounting over time.
• Seismic certification for critical environments: This rack is certified to meet seismic requirements, making it a trusted choice for facilities located in regions where movement or vibration control is essential for equipment integrity and uptime.

how to install Middle Atlantic 40 RU WRK-SA Series 24-1/4 Inch Wide Rack, 32 Inches Deep without Rear Door

• Choose a suitable location: Select a level, stable floor with adequate clearance for front access, rear cable management, and proper ventilation. Avoid spaces with high vibration or extreme temperature fluctuations.
• Unpack and inspect: Remove packaging carefully and inspect the rack for any shipping damage. Confirm that all mounting hardware and accessories included with the WRK-SA are present before installation.
• Position and secure the rack: Place the rack in its designated area and, if required by local code or facility standards, securely anchor it to the floor or adjacent structures. The stand-alone design allows flexible placement, but stability should always be confirmed before loading.
• Mount equipment: Install standard 19-inch equipment rails as needed, following the equipment’s front-mounting guidelines. Start with heavier items at the bottom to maintain a stable center of gravity and simplify cable routing.
• Route cables and power: Plan cable pathways to minimize congestion and maximize airflow. Use appropriate cable management strategies to keep power, data, and AV cables organized. Connect power distribution units (PDUs) and network gear as required, ensuring weight distribution remains balanced and the front of equipment remains accessible for maintenance.
