Personally, I wouldn't want a court holder style like that as it's going to wear your cables insulator jacket eventually since that's just rubber. Any hard plastic with 90° edges will eventually start to wear the cord at the same spot.
There are plenty of options you can connect to the wall that allow you to wrap around and then plug the end of the cord into it just like some of the high power wall connectors have. That's the style I would go with and it's the style that I have as well. You can get them on Amazon super inexpensively.
