Double rocker laser-engraved. For all switches and remote controls, we provide double rockers in all available switch and remote control colors with laser engraving. Prints with a maximum of 6 lines must be described, and we will engrave them in the Arial font. A maximum of two lines can be placed at the top, in the middle, and at the bottom. If we receive an Adobe Illustrator or Corel Draw file with the extensions .ai or .cdr via email, we will also engrave custom specifications from customers.
