Yamazaki Ladder Hanger, Steel, White, One Size

I am wondering how far from the wall this sits (as in how deep)? If I could get the depth of the bend at the top that'd be peachy!

What are the dimensions?

Is the ladder water resistant if I place it outdoor (e.g balcony)?

Is this suitable for hanging blankets on all 5 rungs? All th blankets we have are full adult size so want to make sure it will not topple over
