This piece will extend the pole 495mm (19.48 inches) higher when added to the main 45mm Pro Quality dance pole.
It is recommended that you use as least amount of extensions as possible to achieve your desired height.
If you have the option to buy a larger extension that will give you additional height while simultaneously replacing the smaller 125mm extension then it is highly recommended that you do so.
This will only fit screw together type poles, it is not compatible with the X Pole.
