Gira System 55 is a modular system with a choice of over 300 functional inserts. The USB power supply can easily and conveniently be integrated into this system, offering you a high degree of flexibility. An innovative concept, each functional insert of System 55 has a square, uniform dimension of 55 x 55 mm. You could, for example, choose a single cover frame and integrate into it different functional inserts. For example, you could have a multifunctional station with a Gira radio and the USB power supply together in the kitchen, the living room or bedroom. Choose between either a rounded or a square frame.
