My pantry cabinet is just deep enough to where the extract bottles always seem to congregate right at the front, just in the way of the can of soup you want. Since there is always this small amount of space why not mount them directly to the door so they move out of the way automatically.
This holder was designed specifically for the Watkins brand of extract bottles, it may work with other brands.
I mounted mine with 3M VHB double sided tape, though other brands of tape will likely work.
