I wasn't sure how sturdy a small pan rack would actually be. My husband loves to cook, so we have a lot of pricey pans we don't want scratched up. I decided to not risk it collapsing and went with trying it sideways as a divider instead.
The design is actually very good. It is very adjustable to your needs, with several slots from which to choose. There are five dividers which can be placed anywhere. One divider has "feet" on it to provide extra support if you plan to use this rack vertically.
I put them spaced out evenly just to give it a try. The rack slid all over the shelf every time I tried to put something in it. So, I happened to have a roll of rubbery no-slip shelf paper liner. I cut off a fairly large piece and put it on the shelf, with the rack in the middle. Yay! No more travelling rack!
Right now, I am using it for cookie sheets and baking racks that I had dll stacked on top of each other. It was nice to be able to separate them.
Overall, happy with this rack.
