Product review (5 stars): Fits like the original
Sometimes the simplest solution is the one that works.
For some reason, after filling the rack with dirty dishes, it would not slide into the tub so we could start the washer.  We were in a hurry so I lifted the rack into the tub, started the dishwasher and went to walk the dogs.
Later, when emptying the dishwasher, less than half of the bottom was clean.  Top rack was clean.
Went into handyman mode. Took apart the dishwasher, cleaned out the trap, grinder, and wash arms.  Found nothing.  It wasn't until I was putting everything together that I noticed the silverware basket has some big holes in the bottom.  After years tossing silverware into the basket some of the plastic sections had broken off.  The silver was falling through, jamming the rack and lower wash arm.  DUH!!!!
Of course it was Sunday when I took on this project.  Not that any of the few local appliance stores would stock this anyway.  Most of the local mom and pop places were gone a couple years after the big box stores came into town.  The big box Depot store told me it was special order.  See ya in a week at double what Amazon was charging.
Ordered it Sunday evening, showed up on my doorstep Wednesday.  Except for the darker grey (and no big holes) this works like the OEM.
