A Trivision sign comprises a rectangular aluminium frame housing a series of vertical three sided prisms under electric motor and mechanical gearing control to give prescise alignment to the prism face.
These prisms can be rotated in either direction to show three different sign aspects.
These signs can be manufactured in different sizes from 415mm to 6320mm wide and up to 4260mm high. They are particularly suitable for outdoor advertising applications with regular changes to their aspects.
They are also suitable for outdoor traffic applications with low power requirements where they change infrequently to advise the travelling public of road conditions ahead.
