I just moved into a new house that has a carport and a storage room (finally!). I am looking for ways to store my full hard doors since I have them off most of the time. I went out to Home Depot and bought 4 wall hangers that are rated at 50 lbs each. The only problem is the storage closet apparently has hollow walls because I can't seem to find a stud. I put one up on the wall just to see how weak it was and after putting a little bit of weight onto the hanger it got ripped out of the wall. Would I be ok using wall anchors or should I do something else?
