Since it is not wide enough for my dishwasher (Maytag model MDB9150AWW), the wheels often fall off the track and into the dishwasher.  However, according to my research, this is the only one available.  This is a Whirlpool part.  It only has 3 wheels on each side.  Whirlpool bought Maytag.  However, I made it work.  I used a hack saw to make the new part fit inside of the old part.  With my customization, the lower rack rolls into and out of the dishwasher properly.
