Unimantles incorporate a flexible heating element allowing for efficient heat transfer and fast boiling times. Ceramic fiber thermal insulation concentrates the heat on the glassware and keeps the metal case stable and cool. Maximum temperature is 842°F (450°C). Include support rod clamp (for 1/2" rod), non-slip feet, and a 6½"-ft (2-m) three-prong line cord.

Note: All models require a heating controller.
