This part is a replacement tine row clip for your dishwasher. The tine row clip is adjustable, and it fits onto your dishrack to holds the tines into place. If your dishrack tine rows will not stay in position, you could have one or more broken tine clips. To replace a tine row clip, simply snap the old tine row clip out, and replace it with the new clip. This part is made of gray plastic and is approximately one inch long and half an inch wide. This part is sold individually, so it is a good idea to check all of your tine row clips to determine if more than one are broken.
