Old thread info, hanging on a wall  

There was a thread in the past year that I've been unable to find in the [search] since I can't remember any of the actual words except "wall" and "hang". It was a thread about covering walls and some suggestion a piece of hanger hardware that had two parts. It was a channel that's put on the wall and a hanger on the thing being hung that slips into the channel. There was a link for the supplier and everything.

I want to use it for a table I'm having made. It would support the console table along the back so it needs only the one leg. Anyone remember?
