Question about Hauck Close'n Stop

Hello, I have just measured my Hauck Close'n Stop 96 - 102cm and the 96cm is the smallest measurement that can be adjusted.
The listed measurements (75-81cm / 96-102cm) should definitely be taken into account for this product, otherwise the set-up is not possible.

I have this product in my holiday home and therefore cannot check it. I have mounted it on a plastered wall with the enclosed plastic discs. These discs are approx. 1 cm thick on both sides. On a smooth surface, it would probably be possible to mount it without these discs and thus the 95cm would also be feasible.
