Middle Atlantic SRSR Series 27RU Slide Out Rotating Rack Rail System - 19.1in Depth Wall Mounted Rack

The Middle Atlantic SRSR Series 27RU Slide Out Rotating Rack Rail System is a purpose-built solution for high-density equipment in spaces where rear access and clean, integrated aesthetics are essential. Engineered for millwork, cabinets, and flush in-wall installations, this wall-mounted rack system combines generous capacity with an exceptionally compact footprint. With a 27RU capability, a slide-out design, and a 90-degree rotation in either direction, the SRSR is ideal for smaller systems that require easy maintenance, thoughtful cable management, and flexible configuration without sacrificing rack reliability or professional presentation. Whether you’re mounting AV processors, patch panels, switches, or audio/video equipment, the SRSR preserves usable space while delivering robust, service-friendly performance. In short, it’s a versatile, space-saving rack solution that makes complex wiring and frequent servicing straightforward and less disruptive to your finished installation.

• Effortless rear access for connections and maintenance: The slide-out mechanism combined with 90° rotation lets technicians reach power, data, and I/O at the back of the equipment without crawling behind the rack. This design reduces installation time, simplifies servicing, and minimizes disruption to the surrounding space, which is especially valuable in wall-integrated environments where access is limited.
• Maximized rack capacity in a compact form: With 27 rack units of usable space, the SRSR accommodates a broad range of standard 19-inch equipment in a single, neatly organized enclosure. This capacity is particularly beneficial for compact data closets, control rooms, or media walls where floor space is at a premium but expansion needs may arise.
• Wall-mounted versatility for millwork and flush installations: Designed to sit flush in millwork, cabinets, or in-wall recesses, the SRSR blends seamlessly with room design while delivering professional-grade cable management, ventilation, and serviceability. It’s an ideal choice for spaces that demand a clean, architectural look along with accessible service points.
• Flexible depth options to fit varied installations: The system is available in 19-inch and 23-inch usable depths, providing adaptability for different wall cavities, cabinet configurations, or in-wall installations. The product title notes 19.1-inch depth, and the option to choose a deeper depth supports more demanding layouts or larger equipment footprints.
• Removable rack frame for in-shop assembly and upgrades: The removable frame enables pre-assembly, testing, and upgrades away from the final install site. This feature speeds deployment, reduces on-site complexity, and allows technicians to stage equipment in a controlled environment before seating it within the wall or cabinet.

How to install Middle Atlantic SRSR Series 27RU Slide Out Rotating Rack Rail System

Preparing for installation begins with ensuring the supporting wall or cabinet structure can safely bear the weight of the rack and its future equipment. Confirm that the chosen location allows full extension and 90-degree rotation without obstruction, and verify that the wall cavity or cabinet has appropriate clearances for ventilation and cable routing. Following the manufacturer’s guidelines, mount the SRSR rails to a solid backing or to the provided mounting brackets, making sure the unit is level and plumb for proper operation. If you plan to pre-assemble the rack frame off-site, you can attach the removable frame in advance, then slide the assembled unit into position when ready.

Once the rack is secured, connect rear chassis cabling as needed while the rack is extended. Route cables to maintain airflow and minimize strain at connectors. After cabling, carefully rotate the rack to its stored position to verify smooth operation and to confirm that all panels align correctly with the wall or cabinet face. Finally, perform a functional check of each device to verify power and data integrity, and secure any loose cabling with appropriate ties or management accessories. Regular maintenance should include periodically inspecting mounting hardware, lubricating the slide mechanism if recommended by Middle Atlantic, and confirming that cables remain neatly organized and free from pinch points during rotation.

Tip: If you expect future equipment upgrades, take advantage of the removable frame to stage new devices in a shop environment. This approach minimizes on-site downtime and keeps the finished installation tidy during transition. Always follow local electrical and building codes, and consult Middle Atlantic’s installation notes for any model-specific requirements or torque specifications.
