Factory OEM Keyboard Cover/Overlay for the SAM4s ER-920, ER-940, SPS-320 and SPS-340. This is the overlay that covers your paper template. If you can no longer see through your old keyboard cover it is time for a new one.
If you also need to make a new paper template and you don't already have the file, add the CD option to you order and we will include a CD with the file to make your own keyboards templates with the keyboard cover.
