The ‘A-mazi-ng’ Picture Hook has revolutionized the way we hang pictures and heavy mirrors on the wall. With this heavy duty hanger, the wire is trapped in a maze, so it abates the wire from jumping off the wall and causing serious injury. The hook features 2 holes: one for hanging lightweight items with a nail and one for heavyweight items up to 100 pounds with a screw into the wall stud. It is super easy to install and remove. Each package contains 4 hooks and hardware.
