The wife went out to ikea and came back with a 200 lb bookcase. After spending the better part of 10 hours putting it together, I was ready to mount it to wall for safety. The bookcase will be close to 700 pounds heavy when full. I stripped off the carpeting section, and actually took off the bottom molding to insure a close fit. The unit has two sort of L brackets(one at either top end )that is attached to unit with two screws and then they expect you to mount to wall with one large cutout hole, with a sort of washer/lock that has a big hole and small locking hole. For these jobs, I usually encounter a wall which is hollow after drilling through and I would use a toggle bolt to insure the safety with this weight. When I starting drilling in, after about an inch, I realized I was into something the drill bit wouldnt penetrate. It wasnt a wood beam, thats for sure, or a wood stud. I went to the other side of book case and tried that side(six feet apart) and got same result. I tried two smaller pilot holes in various locations and everything is that way, so I am assuming I am hitting concrete/cement, as a beam I dont think would be that large. How do I mount this unit, into concrete if that is what I am looking at. I dont believe its brick or metal. Thanks for any info provided. Much regards
