I need to hang a 5ft Mantle/Shelf unit in my family room (on drywall). The shelf is heavy however, and I'm afraid the hardware that was provided (plastic plugs w/screws)will not support the shelf. The shelf has 3 keyhole brackets on the back. I need to center the shelf over a couch, and odds are the keyholes will not line up with studs. What is the best solution? I admit that I am not handy, and will likely hire someone to do it right (more peace of mind). Any suggestions?
Try to catch at least 1 stud with an el bracket screwed onto the back of the shelf, the other end screwed into the stud. You can alway's hide the bracket later on once the shelf is up. Winged toggle bolts are good also when going into drywall. Good Luck, Tom
