I have a small house and have been trying to find ways to use the space I have. I bought these drawer slides to make a retractable broom holder for my small laundry room to keep my brooms and rags from falling across the room. They didn't bring any hardware, but luckily my husband happens to bring screws, bolts, nuts, and washers home from work in his bag, so I have plenty of stuff to work with. I screwed one side to the wall and the other to the board with tool holders. bam Individual retractable broom holder. And it's not plastic. Durability - now remember this is not how it's meant to be used. So if it was a regular box with 1 on each side I'd say it would be fine. For the way I've used it, it's a bit inferior. It glides smoothly and makes no noise when sliding. It was easy to install and I am happy with my purchase. Would buy again.
