If you are apparently, be aware that the thickness of the door frames is typically 6.5 cm. Announced for door frames between 6.1 and 8.1 cm, values are quite fanciful. You will need a 10cm door frame, according to my calculations so that the bar lies flat against the door frame and the wall.
For information, the device is supposed ideally supported a maximum weight of 100 kilos.
Sold as a drawbar, ultimately it is fully usable for floor exercises in my case.
