Busy exhibitions need not only a great deal of planning and organisation, but the most successful exhibitions also ensure that effective communication takes place to visitors and delegates. There are a number of ways to do this, from your PA system in the exhibition hall, through to trade magazines, electronic maps of the exhibition stands and areas in the welcome area to the exhibition hall, all the way through to items such as our A4 sign holder for chrome retractable belt barrier. This A4 sign holder screws into the top of the retractable barrier, into which you are able to put any message, brand advertising, map, timetable of events and so on – these are particularly useful for when visitors are in the ticketing queue, for instance, and you want to get your message across.
