Product review (5 stars): Superior to the original design.
I ordered this as a replacement for the rack adjuster that failed in my Whirlpool dishwasher. The original piece was all plastic and became brittle. This new piece is constructed of a metal frame and seems to be designed much better than the original part.

Replacement was not difficult. I completed the job in around 30 minutes by myself.  The job requires a size 6 Torx driver, but the kit comes with an adapter for a phillip's screwdriver.
