I found this hanger holder when I was looking for a wall mount hanger to hang shirts I'm hanging up when I take them out of the dryer.
Here is the cool wall mount hanger thingy that I bought. You can have it straight out or slanted down like it shows in the picture. It folds up or down (I can't remember which) when not in use.

This one looks cooler and holds more hangers but the white plastic one fits in my cabinet in my laundry room and was about about a 1/3rd of the price.

Beg, where the heck have you been these last 10-12 years.?
All of these items I have had For YEARS. The device is suppose to hold up to 20 lbs. and does work. One can gain a tremendous amount of space in small hall closets and if you have a walk in closet gain enough space to actually see what clothing you have.
As far as the hanger storage, Hubby took a piece of left over 2x4 added a couple dowels and for $2.00 replicated the item for storage of those darn things. And Yes it is not an Urban myth, when placed in a dark closet those things breed like rabbits. One day 3 hangers, 2 weeks later 22.
