Product Overview
The Chief FCAB3X1U is a Fusion ceiling-mounted add-on accessory that retrofits a single-sided 3 x 1 ceiling menu board into a back-to-back, double-sided configuration. It is built for digital signage menu boards in locations where walls are not available, such as quick-service restaurants, commercial meeting space, and retail. The accessory fits screens from 40 to 55 inches, with FCAX extension brackets available for larger screens up to 65 inches.
Product Description

Chief Fusion ceiling-mounted solutions make it possible to build menu boards in prominent, high-visibility locations where wall space is unavailable. The FCAB3X1U add-on transforms an existing single-sided LCM3X1U 3 x 1 ceiling menu board into a back-to-back LCB3X1U solution, doubling viewing surfaces without adding floor or wall mounts. A single horizontal extrusion keeps all screens aligned across the row for a clean, professional video wall appearance. Tilting interfaces with Centris technology allow easy adjustment from plus 5 to minus 20 degrees to optimize sightlines for seated and standing viewers. Tool-free screen engagement speeds installation and service, and a padlock can be added to secure each screen to the mount in public spaces. The accessory fits screens with 40 to 55 inch diagonals out of the box; add FCAX extension brackets to support larger screens up to 65 inches. Confirm screen compatibility using Chief MountFinder before ordering.
