can always use more
Color: Black
I keep buying more of these for fitness equipment storage. I got long and short hook models and very strong magnets hold up pull down attachments weighing 10lbs or more. Works great for belts, carabiners and anything you want to organize in the weight room.

Definitely holds 5lbs, but not 8 lbs.
Color: Orange_J_Hooks
It holds my 3lb weight, also my 5lb weight. But it doesn't hold them both - 8 lbs- as it slides off my metal door.
