The Proximity Large In-Wall Storage Box PAC526 is designed to support the professional installation of flat panel displays by offering a recessed, secure, and organised space behind the screen. It allows for effective routing of excess cables and provides mounting options for power-related accessories such as surge protectors and power conditioners. This makes the Proximity Large In-Wall Storage Box particularly valuable in commercial AV environments, where infrastructure reliability and maintenance access are critical. The unit supports installations that require clean, concealed cable organisation without compromising on accessibility or compatibility with AV hardware. Its design allows it to integrate with a wide range of Chief wall mounts, including PST, PRO, PLP, MSR, MTR, MWH, MWR, PWR, PNR, PDR, Thinstall and Fusion series. This versatility makes it suitable for deployment in boardrooms, control rooms, education facilities, and corporate offices. By centralising essential AV components within the wall cavity, the Proximity Large In-Wall Storage Box contributes to a more streamlined and professional installation. It also facilitates future servicing by keeping cabling and equipment neatly housed and easy to access. Built to meet the functional demands of commercial AV integrators, the Proximity Large In-Wall Storage Box ensures installations remain efficient, tidy, and compliant with project requirements across various industries.
