Without knowing what exactly your "TV Hanger" is and does it is sort of tough to say for that one.
I use an Omni-Mount flip down mount and leave the TV hanging all the time.
I also have a fairly new lighter TV and they are getting lighter every day.
This has been discussed here over and over and I would search for the posts before deciding factoring in the weight
of your specific TV and function of your mount and its installation.
