Grab a pencil or a marker and take note of the bottom and top corners of the mirror.
How to hang a large frameless mirror on a wall.
Reposition the mirror to its original location and screw the other end of the cable to the top of it.
Slide the frameless mirror into the two bottom j clips pushing down firmly to lock them into the clips.
Screw one end of the cable to the wall anchor.
Use a screwdriver or drill to tighten the top two clips so they are no longer loose.
It would be easier to go through this step if you have someone to help you on the side.
Place 2 clips on the bottom 1 on each side and 1 on top for most mirrors though a large mirror may need more.
Mark the location of the top edge and the center of the frame.
Jiggle and slide the top two clips down over the top edge of the mirror securing it against the wall.
To use clips put the mirror where you want to hang it and use a pencil to mark the top and bottom corners.
You can now place the mirror back in its place.
Remove the mirror and put another mark two inches below the first mark.
Make a mark where you want the mirror to be.
This requires attaching d rings to the back perimeter of the mirror frame wrapping wire around the d ring and then attaching one or two hooks to the wall and hanging the mirror by the wire.
Place a scrap piece of wood that is approximately half as long as the mirror is wide underneath the hanging wire on back of the frame.
Set the mirror down.
Hold the mirror against the wall at the desired position.
D rings and picture wire the mirror must have a frame around it to hang a mirror this way.
Keep one hand pressing the mirror against the wall.
