Beginner Needs Help - Drywall Anchors
I'm not handy but decided to install a closet organizer kit in the bedroom of my Manhattan apartment by myself after a number of equally inept friends told me it was easy. The kit involves a shelf system that hangs from a long support that you're supposed to screw along the top of the closet wall.
After drilling into the drywall, I reached concrete about an inch and half in. From what I can tell, there is 1/2" of drywall, an inch of air, and then concrete. What type of drywall anchor will hold a lot of weight but will only require a screw that is an inch or an inch and a half long? I looked at 1/8" toggle bolts but the minimum length screw that I saw was 2". Help! I'm surrounded by clothes and have no place to hange them.
I was told by the retailer of the closet kit that I could drill a hole in the concrete and then use concrete screws but that would be extremely difficult. It would also require me to notify the building's board, get permission, and then obtain insurance. After agreeing with the retailer that the concrete screws were not the best option, they proceeded to sell me a different type of their brand of anchor, which also doesn't fit.
Any advice you can give me would be much appreciated.
