No, the disc holders are not included in the 176cm length. You can add approx. 23cm per disc holder.

No, the rack cannot be adapted to an uneven floor, you would have to put something underneath it, but it's questionable whether that makes sense because of the stability etc. Otherwise, the product is top and to be recommended. Price - performance is right. I have been using it almost daily for two years. Greetings

Unfortunately, the manufacturer does not indicate whether the bar can be mounted the other way round. Therefore, we do not recommend mounting it upside down.

I use the rack indoors.

Hello, yes, these can be removed without complications. Best regards
