Middle Atlantic SR Series 46RU Large Pivoting Rack – 32in Depth Wall Mounted Rack

Designed for professional environments where accessibility, capacity, and reliability matter, the Middle Atlantic SR Series 46RU Large Pivoting Rack delivers a premium solution for AV, IT, and broadcast installations. This wide pivoting wall rack is built to maximize space efficiency without sacrificing serviceability, providing straightforward access to rear cables and equipment. With a large 46U footprint, substantial load ratings, and a 90-degree pivot mechanism, it’s the ideal choice for control rooms, media studios, data centers, and busy server rooms where uptime and organization are critical.

• Large 46U capacity for scalable equipment layouts — a generous 46 rack units of space accommodates servers, network gear, patch panels, UPS devices, patch bays, and AV equipment in a single, organized enclosure. The expanded footprint makes it easier to plan future expansions while keeping cables tidy and workflows efficient.
• High-strength load and seismic ratings — engineered to support demanding installations, this pivoting rack offers a UL load capacity of up to 500 lb and a seismic load capacity rating of up to 335 lb. These ratings provide confidence in maintaining gear integrity under normal operation and in compliant environments that require seismic resilience.
• 90-degree pivot for rapid, unobstructed access — the rack pivots open 90 degrees, enabling effortless front-to-back service access. This design minimizes the need to disconnect equipment during maintenance, simplifies cable reconfiguration, and reduces downtime during upgrades or repairs.
• Deep 32-inch chassis for deep equipment and cable management — with a substantial depth of 32 3/8 inches, the rack accommodates rear-access hardware, extended power distribution, and ample cable management space. This depth helps keep cables organized, improves airflow, and reduces strain on connectors and ports.
• Wall-mounted with floor-base support for stability — engineered for wall mounting while providing a stable pivot base, the SR Series combines space efficiency with solid support. This makes it well-suited for rooms with limited floor space, studios, control rooms, and other environments where a freestanding rack would be impractical.

How to install Middle Atlantic SR Series 46RU Large Pivoting Rack

• Preparation: Confirm the wall structure can support the combined weight of the empty rack plus configured equipment. Plan the layout to place heavier components toward the bottom to maintain a stable center of gravity.
• Positioning: Measure and mark the mounting locations. Ensure there is sufficient clearance for the 90-degree pivot and that cables will have ample slack to accommodate the pivot motion without strain.
• Mounting base: Secure the floor-based pivot base to the floor at the intended location. Use appropriate anchors and fasteners compatible with the floor material (concrete, wood, or other surfaces) as specified by the manufacturer.
• Wall attachment: Attach the rack frame to the wall using the supplied hardware. Verify level and plumb alignment, tightening fasteners in a sequence that preserves frame rigidity and prevents skewing.
• Rail installation and equipment mounting: Install rack rails and any vertical cable managers or accessories. Begin loading equipment from the bottom, ensuring even weight distribution and leaving room for air-flow and cable routing.
• Cable management: Route power, network, and AV cables with dedicated channels or cable ties. Maintain separation between high-current power lines and data cables to minimize interference and heat buildup.
• Pivot testing: Slowly pivot the rack to the 90-degree position, watching for any binding or interference with cabling. Re-tighten fasteners if necessary and confirm smooth operation through multiple pivot cycles.
• Final checks: Verify all equipment is securely mounted, all cables are properly organized, and the door/pivot mechanism operates freely without obstruction. Test the setup under load if possible (with appropriate safety precautions) to confirm stability.
