Product review (1 stars): DO NOT GET THIS ONE. Better part available.
DO NOT  GET THIS ONE. It will break again. Its a poor design and you will need to replace in another 1-2 years. Instead get: Whirlpool, Kenmore, KitchenAid - Dishwasher Replacement Rack Adjuster Kit # W10712394. It is a metal design and should have been used in the original. Watch the youtube video "Dishwasher Replacement Rack Adjuster Kit # W10712394 V-rail" as the instructions with the kit are hard to follow.
