The Wohler H 420 Handy Viper is the perfect tool
to clean flue gas systems or ductwork. Before
working with the Viper, stars and brushes can be
mounted.
The exact position of the star or the brush in the
duct will be indicated on the screen, so that the
user knows how many feet into the flue way or
ductwork the rod has traveled.
