Action RPG Inventory System

I’ve been looking for an equipment system like this to add to my project. I noticed in the master item list that the equipment objects have a skeletal mesh asset to associate. Most of my items are only static meshes. Is this system usable or will I have to start changing things to make it work without the skeletal mesh?

Also noticed there is no socket to define in order to attach the items on the character skeleton. Maybe someone who has used this inventory system can give me some feedback before I commit to this.
