Replacement extension poles are available for all Silky pole saws.
The extension poles come with all the parts including clamps and buttons where appropriate.
The 6.1 metre Hayate has four extensions. The top extension (S) middle extension (M) lower middle extension (L) handle extension (LL)
The extensions from the different length polesaws are specific to that size pole saw.
They are not interchangeable between different length Hayate pole saws
The bracketed letters (S) (M) (L) (LL) refer to the circumference of the extension and tell you which size clamp will fit on the pole.
All of the extensions marked (S) are the same circumference but different lengths for each pole. The same for (M) (L) (LL)
