The balance arms, with a maximum length of 11ft., can be mounted to a wall or table by means of a bracket and are ideal for the extraction at fixed workspaces. The arms are made up of two gas damper balanced sections. They have three swivel points, making it easy to move the arms to any chosen position within their reach. To overcome larger distances, a balance arm can be connected to an extension arm with a length of 8ft.or 11ft.
