Although it looked a little flimsy at first, after screwing into place it felt sturdy and secure! Two ways to make it more secure would be to require 2 screws per location (during manufacturing), or to add a u-shaped strap or tie-down of some sort later (during installation). We'll see if something like that needs to be added later, but it feels quite secure now. I added 2 pix of after installation and before adding items, and 1 of after adding items. I installed both the Rev-A-Shelf double tier sliding shelves and the kitchenware divider myself (middle-aged female with moderate mechanical skills)! The divider was easy peasy, especially since I drilled pilot holes first. I put a melamine tray and a plastic platter in the slots, to see the divider in action and to add to this review - they were just what was at hand - I haven't used it with metal items yet, but it feel secure enough that I'm confident that it'll be just fine. Very pleased!!! Highly recommend.
