I'm looking for a piece of cabinet hardware, but I don't know what to call it. Its function is to limit how far the cabinet door can open, in this case to 90 degrees, so that it doesn't hit the adjacent wall and scar it. Here's a picture of what I have in mind:
I know I have seen these before; I've also seen a variation where the slotted piece is a bar with a flange on the end. I can't find anything like this in the hardware stores I've visited, nor can I find them on- line. If there's a proper name for it, I'd have an easier time asking for it and searching catalogs.
So, can anyone tell me what these things are called, and perhaps suggest a source for one?
