Adjustable/swivel fitting for projector mount

This is an adjustable/swivel fitting designed to attach to a projector mount system, allowing the angle or position of a ceiling- or wall-mounted projector to be fine-tuned after installation. It would typically be used by AV installers as a spare or replacement part when fitting or servicing projector mounts in classrooms, boardrooms, or similar settings. The fitting provides a way to adjust alignment without needing to reposition the entire mount bracket.
