MFGD20
I have used their hangar picture frame system and it is really quite nice and no nail etc… needed and will not fall down if you follow the instructions. So this is ideal for people in rental properties who would like to put up various artworks around home.
You can also get a customised size frame from the website.
Now they have 20% off I just ordered another one :)
If you are a great wood worker you might also be able to create this yourself at home, I am not :)
