Each installation requires a flush box for the panel to be secured to the wall. Back boxes are available for all panel options and are constructed from zinc plated aluminium. They are provided with sliding hinges, as shown in the photo, which support the panel while the installer is wiring, making the installation easier. They include sliding hinges and have cable entry knockouts, for cable entry at the most suitable points. In the case of installations where several panels are combined, joining bolts provide a perfect coupling between them. A joining bolt set is required for each additional panel.
