The Chief CMS492 is a specialized suspended ceiling storage box designed for professional AV installations to house and protect electronic equipment within a standard 2' x 2' or 2' x 4' drop ceiling grid. This unit provides a secure, accessible, and ventilated enclosure for power supplies, signal distribution amplifiers, small format switchers, control system processors, and other ancillary AV components that need to be located near displays or projection systems but kept out of sight. By integrating these devices into the ceiling plenum space, it maintains a clean, uncluttered aesthetic in rooms such as classrooms, conference rooms, and corporate lobbies, while keeping critical equipment organized and serviceable. The box is constructed from heavy-gauge, perforated steel to allow for adequate airflow to prevent heat buildup, which is essential for the reliable operation of installed electronics.

Installation is streamlined for compatibility with standard T-bar ceiling grids. The CMS492 typically includes integrated mounting tabs or a frame that rests securely on the ceiling grid, allowing it to be installed quickly without additional support hardware in most cases. A removable lid or door provides full access to the interior for equipment installation, cable management, and maintenance. The interior often includes pre-punched knockouts or cable ports for neat routing of power and signal cables into and out of the box, and may feature mounting rails or pre-drilled holes to secure equipment using standard rack screws or bolts. This thoughtful design ensures that installers can create a professional, reliable, and serviceable hidden equipment location.

The box is designed with safety and compliance in mind, particularly regarding the use of plenum spaces. If the ceiling is an air-handling plenum, all equipment and cables placed inside the box must be rated for plenum use (UL 2043). The perforated design aids in compliance by not restricting airflow significantly. By consolidating equipment in a dedicated, ventilated ceiling enclosure, the Chief CMS492 solves common installation challenges related to equipment placement, thermal management, and service access, contributing to a higher quality, more reliable, and aesthetically pleasing AV system integration.
