Fretted trays combine the elegance of lacquered aluminium fronts with the possibility of adding volume to the letters, having them protruding from the front, with combinations with vinyl lettering, etc...
Trays fretted on one side in aluminium are cut out at the front so that they can be illuminated by the LEDs inside. The options available have the acrylic at the front, which can either protrude from the front, or be integrated inside. An option also exists of closing them at the back with a PVC back or aluminium counter-tray.
ILLUMINATION: Interior illumination is with sealed LEDS, normally white, but it is possible to choose different colours and even RGB. They work on 12 volts, connected to a 12v/230w transformer supplied and which connects to the power supply (230w).
