CLEAR FRONT UNBREAKABLE SIGN HOLDERS Sign cards are fully enclosed, making it possible to use larger sizes without the fear of thin sign papers falling out of the holder. Crystal clear butyrate is more rugged, flexible and scratch resistant than traditional acrylic signs. And these sign holders cost less than acrylic holders. The dual channel on the back provides a choice of mounting position. Fits scanner hooks, all mounting clips and easel adapters.
