Review on Efficiently Hang Pictures on Plaster Walls with Heavy Duty Picture Hangers - 100 lbs - 10 Pack - OOK Hanging Hooks by Tommy Almasri

We have a 20 kilo ladder but we live in an apartment so we had to be careful the weight didn't pull the hangars out of the wall. The weight of these 100# hooks may have been more than I needed, but it worked. God saves the man who saves himself. I later realized that I needed to lower the ladder a bit and was a little worried about the mark those nails would leave; However, you won't see any holes. I highly recommend this especially if you are staying in Apt.
