These special connecting - bolt junctions may be used at the top of an Ego display as a solid, secure point of attachment for cables.
Some displays are suitable for hanging from the ceiling via this connecting point. In other cases, it may be desirable to anchor a display to a wall or ceiling using this same connecting-point junction.

To secure the wing to the construction, insert a metal wire here.

Installations of these types should always be coordinated with the proper authorities in charge of the exhibit space.
