Kittec Extension Rings – CB S Series and SQ Squadro
Kittec extension rings increase the usable firing height of your kiln retroactively, without the need to purchase a new kiln – providing more space for tall pieces, series, or hand-built ceramics. They fit exactly between the kiln body and the lid and are insulated without ceramic fibers.
Thanks to the precise fit, the heat balance remains stable. Installation is tool-free – simply place it on, close the lid, and fire.
