Q:

Hanging 20" x 16" glass pane

I have a 20" x 16" glass pane (that is somewhere near a 1/4" thick) that needs hanging on a wall. The glass pane is actually a holographic image.
I remember seeing a compression/spring mechanism for hanging non-framed pictures that had clasps for each of the 4 sides of the shape and an X spring design to keep pressure even while providing a hookable mechanism some years ago but can't seem to find anything similar in a web search now.
What is the recommended way of hanging something of this size and weight these days?

A:

The item you remember is called Swiss frame clips and still commonly available.
 
The other usual option is a standard method of attaching large glass objects to walls - mirror clips. Fancy or crude.
