Knobit Jeweler's Smiths Silversmith Knob Only for NE-180 & NE-180A

Knobit is a larger acetylene torch knob that goes over your existing Smith torch knob for better single-handed control of your flame. This unit is designed and made to fit only the Smith torch style #NE180 or #NE180A with the standard knob/valve assembly. 

 

Directions for installation: Push the Knobit over your existing Smith torch knob, it should snap and have a tight fit. You might need to exert some small force to push it in.

 

This Knobit is made out of tough 3D printed resin, which should withstand normal use and high temperatures.
