Good to know! :
- Only able to fit this on a sisalpost with a 20Ø
- Gives a margin of 20cm to adjust the height
(If your cat tree is unstable, it's 9/10 times not because the ceiling tensioner is not long enough, but because the ceiling height is above the standard measurements of our products, 245-265cm. Always measure the height of your ceiling before ordering a cat tree with a ceiling tensioner)
