I need to install brackets inside a walkable closet to place an additional closet rod. I am a complete newbie in DIY. I went to the hardware store, and they gave me some plastic anchor that I was supposed to put in the wall with a hammer. But the wall is way too hard and, as you can see from the photo (http://ift.tt/2lQgWMs), I just created a small hole.What kind of wall is this, and which anchor should I buy?I don't have a power drill, so any solution that does not involve the purchase of a power drill would be better :-)Thanks a lot! via /r/DIY http://ift.tt/2lxdy84
