The Chief FCAVCA Variable Column Adapter is a specialized mounting accessory used in commercial audiovisual installations to safely attach Chief mounting solutions (like a Fusion ceiling plate) to structural columns or pillars in a building, rather than a flat ceiling. This adapter is designed to accommodate a wide range of column widths, supporting a span of up to 19 inches, offering flexibility in challenging installation environments where traditional ceiling mounts are not feasible. It ensures a secure and stable mounting point for displays, projectors, or other A/V equipment.
