I wanted to hang some Barack Obama pictures on my office wall, but I wanted to have a flexible wall hanging system so I could change the arrangement.
I ended up with a system from
AS Hanging Systems.
First up is the Wal Track A1005KC which costs $22.50
There are (12) holes in the track to secure to your wall.
I made it level.
Then attached the Self-Gripping Hook (Small $7.25 each) to the J-End Stainless Steel Cable 48" / 120cm ($6.40 each)
Then the hook attaches to the track.
Attach the Self-Gripping hook to the picture frame.
You're done!
