Standard Plate Kit:

If you have pierced or overheated your Lotus hot plate, here's the fix. This hot plate fits all vapor caps, past and present.

Sunburst Plate Kit:

Do you want to dress up your Lotus? This is the original hot plate and fits all of the Lotus vapor caps. This looks a lot better than the standard hot plate but doesn't last quite as long. Just the thing for your next black-tie event. 

What's Included:

  • hot plate (standard or sunburst)
  • wrench
  • 3 screws
  • instructions

Easy replacement.
