Designed by Input Club—the designers of the Infinity ErgoDox—the plates are specifically sized to fit all versions that have been available on Massdrop. The Infinity ErgoDox has an added LCD panel that isn’t found on other ErgoDox models, making these plates compatible only with the Infinity version. Assembly is easy: Simply remove the screws on your keyboard and replace the existing acrylic layer currently on top. There's no need to de-solder switches or remove keycaps for installation.
