Trial and error, I would not mount it in the drawer so its impossible to remove however.

Generally the larger pieces of crockery are heavy so that the piles of them don't move unless Godzilla (or a teenage boy) opens the drawer with a lot of speed.

Instead of that system I just used the IKEA drawer liner that eliminates any plate sliding.

One of my customers did the same as Beverly. She uses those spongey shelf liners...everything stays put fine.

stacks of plates are heavy.... you don't want to stack them deep or they'll weigh a ton, no matter how well the drawer is made. and a short stack just doesnt shift much. only in cartoons is this a problem.

FWIW, when I asked my cabinet maker about using these he told me that most of his clients don't like them because they take up a lot of interior drawer space. The drawer liner suggestion above sounds more practical.

I've never used one of these, but I'd imagine it to be somewhat impractical.

When getting a plate out (or replacing one), your motions are not raising it vertically, before moving it towards you, like a forklift. Typically you'd move it at a natural angle, which would be prevented by these protrusions.

Try it out first, with nothing permanently affixed.
