This part is a replacement axle adjuster for your dishwasher. It is made of white plastic and is approximately ¾ of an inch long and ½ an inch wide. The axle adjuster attaches to the dishrack roller bracket and allows the roller to turn. If the axle is damaged or missing, the rollers will not turn, and it will be difficult to roll your dishrack in and out effectively. This part is sold individually and is an OEM part sourced directly from the manufacturer.
