To order the correct section please count the section the brush screws on to as section 1, 1st clamp as section 2, 2nd clamp as section 3 etc.
Each section comes complete with fittings. i.e. top section with German thread, other sections with clamps and clips.
For smaller poles these sections will have to be trimmed for correct length.
Once trimmed these sections cannot be returned.
Small hacksaw recommended.
