Middle Atlantic AX-SXR Rack Frame: Retractable 4-Post In-Wall Rack System

The AX-SXR-30 is a versatile audio and video equipment installation solution designed for use in cramped areas. Built to maximize space without sacrificing accessibility, this 4-post rack frame pulls out from an in-wall installation and turns to provide greater access to equipment. It’s a flexible, space-saving answer for professional AV setups, home theaters, and compact control rooms where traditional racks struggle to fit. The AX-SXR combines sturdy construction with smooth operation, enabling techs and installers to position gear exactly where it’s needed—without contorting around a fixed wall enclosure.

• Retractable in-wall design: An innovative pull-out mechanism lets the rack extend from the wall, delivering immediate access to front and rear connections while keeping the cabinet footprint small when stowed.
• 4-post, 19-inch compatibility: Designed to accommodate standard 19" rack equipment, including switches, patch panels, AV processors, power distribution, and modular cards, all mounted on a robust four-post frame.
• Turn-and-access workflow: The turning feature provides superior reach and visibility, enabling technicians to service rear cabling, route cables, and swap components with minimal disassembly.
• AXS-series-inspired versatility: The AX-SXR inherits practical design cues from the AXS Series, delivering familiar aesthetics and mounting philosophy with added turning flexibility for challenging installations.
• Durable construction and organization: Built from heavy-duty steel with a durable finish, the frame supports organized cable management and durable rack-mounting, reducing wear during frequent service and reconfigurations.

How to Install Middle Atlantic AX-SXR Rack Frame

Installing the AX-SXR Rack Frame is a practical process that prioritizes safe access to equipment and clean cable management. Begin by planning the wall opening to accommodate a standard 19-inch rack frame, ensuring there is sufficient depth for the in-wall cavity, extension mechanism, and ventilation around mounted gear. Verify structural support in the selected wall area—this solution relies on sturdy framing to safely hold equipment as the rack extends and turns.

Next, prepare the wall opening and secure the AX-SXR frame into the wall cavity using the provided mounting hardware and recommended fasteners. Align the frame so that the rails and posts are plumb and level, preserving proper rack alignment for all mounted devices. Once the frame is securely anchored, attach the front and rear rails, ensuring smooth sliding action and firm attachment points for future gear changes.

With the frame in place, install your 19-inch equipment on the four posts, following standard rack-mounting practices. Leave appropriate clearance for cabling and cooling, and plan cable paths that minimize bending and strain on connectors. Connect power, data, and AV cables to their respective devices, then route cables along integrated management channels to maintain a tidy, serviceable environment.

To use the system, gently extend the rack from the wall until it is safely accessible, then rotate or turn the frame as required to reach rear ports or components. After maintenance or upgrades, retract the unit fully into the wall and re-secure it to preserve a clean, professional appearance. Throughout installation and use, observe local electrical and building codes, ensure adequate ventilation around mounted equipment, and avoid overloading the structure beyond its intended capacity.

Maintenance is straightforward: periodically inspect mounting points for loosened fasteners, verify that extension and rotation mechanisms operate smoothly, and check cable management channels for wear or obstruction. The AX-SXR is designed for repeated service and relocation, so routine checks help preserve performance and extend the life of your installation.

Frequently asked questions
