Are these brushes effective for use in rectangular flues?
By Collin C. - NFI Master Hearth Professional on October 22, 2012
Unfortunately, these brushes are not effective for use in a rectangular chimney. You would need to use the Viper adapter
and chimney rod connector
to make the connection to a standard 3/8" rectangular chimney brush of the proper size for your flue.

Does this brush collapse to fit up past the damper and can it bend through a 45 degree angle?

Answer:As this brush is made specifically for the Viper cleaning system, it serves very well in offsets. However, the brush itself is a bit rigid and only offers minor collapsibility when pushing through dampers.
