I'm not exactly sure how much weight it can hold, but ours feels very secure. Plus its easy to remove if you want to change things in the future.
I also added one of the 3M Command large hooks to the door for Parker's backpack. They are suppose to be a damage free solution for hanging items. You can remove it anytime without damaging the wall or leaving a sticky residue. His backpack isn't too heavy yet, so we haven't had any problems with 5 lb weight limit on the hook.
We store our board games in our coat closet too. What's everyone's favorite board game? If it isn't obvious, we love Settlers of Catan. We have a few different versions of the game. I also love Apples to Apples!
