These mesh organizers are used for medication trays in our hospital. Emergency truck trays and other special medicine trays contain small light-weight vials (1ml, 2ml, 10ml) and other consumables. I've used all kinds of dividers to make trays, but they all fell apart, didn't adjust, and got dirty. They fit perfectly in height (about 2 inches) and the length also fits trays (about 17 inches). I could use a little longer, but this is the best solution I've found.
