Product review (5 stars): Should have designed with this bracket originally.
This is the only way to go if your upper rack is broken.  The original design, using the plastic bracket, is flawed.  The engineer who designed this did a poor job and selected weak polymers.  Replacing with the same part will only result in you having to fix this again.

This was a quick install - I had to do it twice though.  The instructions are for a Whirlpool but we have a similar Kenmore.  I needed to put the bracket thru the 5th set of tines, not the 4th.  No biggie.  Wife is happy - I am happy.
