These are over-the-door hooks that can be hung on a 20mm IKEA Pax door. The hook has an aesthetically pleasing curve which gives it an increased load carrying capacity over a non-curved hook.
There are two sizes: 83 and 122mm
In all models the back of the hanger is angled by 5 degrees so that it grabs onto the door a bit for a snug fit.
The author remixed this model.
Changed to fit 20mm IKEA pax doors.
Increased thickness of the section to increased strength.
Next to the original 122mm version, now also a shorter: 83mm version
