They make drawers close softly, but there are a few tips and tricks to know. As previously mentioned, you will need to place a 1 x 4 x 8 inch piece of wood between the existing drawer slide and the inside of the cabinet. This is necessary so that the closer adapter has something to attach to. A block of wood is easier than any other type of spacer. You also need to carefully align the portion of the drive that attaches to the box itself. All you have to do is clean the front of the soft close adapter attached to the cabinet. If the drive is too high, the drawer is more likely to "jump" off the soft close adapter track and detach from the two arms that guide the drive. During installation you will need to pull the adapter mechanism forward to allow the drawer to be inserted. The same movement is required if you accidentally pull the box out of the adapter's handles. I've found that you need to make sure you're pulling out the drawer and not lifting it to avoid problems. The adapter also adds some extra force when opening the drawer. This jerk occurs when the drawer drive pulls the adapter mechanism forward and locks it in the ready-to-close state. The instructions are pretty vague for the most part, but once you get the hang of it, the adapters install quickly. I've also noticed that the adapters seem to give the small light box more resistance, but the larger box with more weight works more normally when opened. Adapters ensure a good closure. In general, I like closers, but there are those listed above, which reduced the rating from 5 to 4 in my opinion. They are a good alternative to replacing the entire drawer slide assembly.
