Note: We no longer manufacture the 6" Extension. However you can "piggyback" the Extensions. If you want a 6" extension choose the 6" Extension option which will include two 3" Extensions.
Chucky Extensions are available in 3" and 6" versions. Each has a 1/4 X 1" hole in the threaded end to accommodate accessories; such as buffers or sanding discs.
When using an Extension make sure you take LIGHT cuts and don't put excessive pressure against the work piece
to prevent from bending the shank of the extension.
