Abstract: Media supply units are described for the provision of media such as electricity, gas, data or compressed air. The units comprise a base unit (1) adapted to be installed in or on a ceiling structure and a media outlet supply head (2) connected to the base unit by means of a flexible support member fixed at its ends to the supply head and to the hub of a spool in the base unit. One or more electrical cables or pipes are also arranged between the hub of the spool and the supply head (2), and the flexible support member is a non-stretch conduit (30) which can be wound on to or from the spool in order respectively to raise or lower the supply head relative to the base unit. When lowered, the supply head (2) may rest on a school desk or table.
