PRO4® is a multifunctional profile designed to address the lighting of spaces where interventions on walls or ceilings need to be limited, such as historic buildings and museum spaces. The profile serves as a support element for four different functions: indirect lighting with linear systems, cable routing (electrical power, telephony, PC network, alarm, speakers…), direct lighting with linear systems or adjustable fixtures mounted on an electrified track, artwork suspension through specific grippers. The base profile is completed by one of the two available finishing veils that allow the electrified track and installed linear fixtures to be hidden from the visitor in the upper part. If necessary, the profile can be requested custom-made. PRO4® can be installed on the wall or supported through pre-spaced holes at a distance of 30 cm, and can have different configurations based on project requirements: it is indeed possible, alternatively, to install in the compartment prepared for the electrified track also a fixed or adjustable direct linear lighting system.
