There were drawers in the closet that fell out if you pulled them out more than halfway. But I couldn't figure out how to get the side rails to work as there was no gap or anything to attach them. But they work well and much better than the originals. I don't think they will fail like the originals. Note: The two bits are probably different lengths. The wider part attaches to the bottom of the drawer and is shorter than the narrow end that attaches to the drawer opening. You need to cut them according to your application.
