Solid Wide-View Peephole Plugs

Wide View into Kiln

  • Peepholes are a 1" in diameter (or 3/4" for some models) with a non-tapered hole.
  • This allows for an unusually wide viewing area in the kiln.

Note the straight wide view of the hole.


  • The end of the peephole features a heat-lock head with helps seal up the peephole.

Solid and Strong

  • All L&L┬áKilns feature these solid ceramic peephole plugs.
  • They are much stronger and heavier-duty than the typical hollow slip-cast peephole plugs you find on many competitors' kilns.
  • Although they can break it is much less likely with these plugs.

Less Chance of Breakage

  • Because the straight peephole plug is parallel to the floor there is much less chance of it falling out of the peephole and breaking on the ground.
