(All panels are the same size)
Because there are many sizes of illuminated wall mounted cabinets and boxes, the panels are larger so they can be cut to size. This should be done with an electric saw. To avoid edge cracking and chipping, masking tape should be fixed through the cutting line on both sides of the panel.
Alternatively, most plastic sign makers will be able to cut the material cleanly and accurately to size. Ensure the letters are covered with soft paper or plastic to avoid scratching the printed letters.
