Good document holders are important tools in every office. Documents used on daily basis can be stored in them in a practical and easily accessible way. Open document holders without case are ususally made of mounted corrugated board or mounted protective plate because it is important that they can stand stable on the table and hold large amounts of documents. Cases are typically made for the mounted version.
By gluing a plastic pocket or rail onto the document holder, indicating the document names or intervals, the documents can be stored more systematically.
