This information is for the Lupit G2 Dance Pole.
This happens to people sometimes so don't worry, there is a solution. :)
To shorten the Lupit G2 Dance Pole, you would need to purchase a 500mm extension to replace main pole B. You will use some or all of your extensions (500mm, 250mm, 125mm) in place of main pole B in order to fit your lower ceiling height.
DO NOT put the smallest extension in the middle of the pole. When using multiple extensions, work from the largest extension to the smallest. For example, first install the 500mm, then the 250mm and then the 125mm on top of the 250mm. If you are only using the 500mm and 125mm, then install the 500mm first, then the 125mm. Always leave the shortest extension at the very top of the pole when installed.
This will shorten the pole to fit ceiling heights:
Replacing Main Pole B with a 500mm fits ceiling heights between 67.33" to 72.25".
Adding the 125mm extension to the 500mm that replaced main pole B fits ceiling heights between 72.25" to 77.17".
Adding the 250mm extension to the 500mm that replaced main pole B fits ceiling heights between 77.17" to 82.09".
Both 250mm & 125mm extensions added to the 500mm replacing main pole B fits ceiling heights between 82.09" to 87.01".
