Product Overview
The Chief SYS474UB is a SYSAU suspended ceiling projector system in black that pairs a preassembled mount and 0-12" adjustable column with a plenum-rated storage box. It is engineered for speed, cutting installation time by roughly one-third and shipping with everything needed to complete the majority of projector installations. The system drops into standard suspended ceiling grids and conceals AV equipment above the tile. It suits classrooms, conference rooms, training rooms, and auditoriums.
Product Description

The SYSAU system was designed for speed and flexibility from both an ordering and an installation standpoint. The SYS474UB comes out of the box in the order needed for installation, with the mount and column preassembled to reduce labor on site. An adjustable ceiling plate allows placement above or below the tile and accommodates inconsistent T-grids, with compatibility for 2' x 2', 2' x 4', 60 x 60 cm, and 62.5 x 62.5 cm ceiling grids. A detachable electric plate supports pre-wiring and is compatible with popular 2-gang adjustable mud rings. Tool-free Microzone adjustment eliminates the need for set screws, and Centris technology enables effortless fingertip projector positioning with a tool-free lock down. The 0-12" adjustable column includes dual inlay channels that separate high- and low-voltage cables, and the Q-Lock quick-release lever provides fast connect and disconnect of the projector for service, with an integrated key and lock system for added security. An improved universal interface makes lock and unlock at the projector connection easier. The included plenum-rated enclosure is scalable to fit AV equipment, shifts along the tile bridge to avoid plenum interference, and offers removable covers for side access in shallow plenum spaces and full access from above. Six trade-size conduit knockouts in 0.5", 1", and 1.5" (12, 25, 38 mm) plus flexible knockouts route high-voltage conduit through the plenum box when the power faces the room below. For the white version, see the SYS474UW, or browse the full Chief collection.
