The saving grace for those, like me, who have no closets and live in tiny apartments. A heavy duty hook to keep my grocery cart on my wall. I was prepared to use two of these for the job but it was strong enough that I only needed one. It takes four screws, the top two of which are accessible to your screwdriver through a hole in the front. Make sure to put this in a stud! 2 shells, 35% infill, no raft or suports.
