Product review (5 stars): Exact Fit
Perfect fit for my Whirlpool side by side. Although it remains to be seen, how well this will hold up without cracking at the "flare out" point, where the tray hangs on the door tabs. The  original trays, all crack at some point, so I have been using the bright shiny metal foil tape which is used for air conditioning duct sealer. It works great to run all over the tray at these crack points, especially since they are paper thin and do not in any way disrupt the use of the trays.  But I got tired of having to replace the metal tape every 2 to 3 years, when the weight of milk jugs, etc would eventually cause the metal foil tape to give out. So I decided to purchase brand new trays to retard the fault. These trays seem to be ever so slightly thinner so they may crack within 3-4 years, like the original trays which came with the fridge. And the cost for these trays from this vendor on Amazon, were 30-40% lower in cost than buying direct from Whirlpool. So it is worth it.
