Folding Poles (named "Micro") use 4 sections for fixed length poles and 5 for variable length models. The lower two sections connect to the rest of the pole with a fixed cord. One section slides out of the upper part and is held assembled with a locking pin mechanism. Variable length poles (called "Vario") have an extra section that also slides out of the upper section and is held in place at the desired length with a locking lever mechanism (Speed Lock or Speedlock 2).
