I have a custom shelf that I built to sit on a desk top but now I want to mount it on the wall. The backing is 1/4 inch plywood. The shelf weighs about 17 pounds and will hold anywhere from 10-20 pounds of items at the most.
Is the 1/4 plywood strong enough to hold that weight with 4 proper anchors? It is only nailed to the shelf but I will attach securely, with many screws.
Also, there are well placed wall studs that I could fasten into directly. Would simple screws going through the 1/4 plywood back and into the studs support the approx. 30-35 pounds max weight?
