The hardware necessary to hang a mirror includes D-rings that screw to the mirror frame and wall-mounted hooks that slip into the D-rings. Hanging wire, D-rings and a single nail are useful for hanging lightweight mirrors.
The weight and style of the mirror dictates the hardware needed to hang it. The D-ring and hook method is appropriate for mirrors with frames. Lightweight framed mirrors usually accept any type of standard picture-hanging hardware, including saw-tooth hangers, molding hooks and high-strength adhesive hanging strips. Mirror clips and hooks are useful for hanging frameless mirrors. Extra-large mirrors or heavyweight mirrors require hanging cleats and nails or hooks.
