The one I saw looks something like this:

Not sure if this is the same product...for me it is hard to see the picture but the concept is the same. It was long rectangles of preformed screen that fit each vent strip for the fridge...if this is it the price is better.
Here is another pic...from another company:

What I did was take metal screen and formed my own screen cover...a large one piece cover to screen the entire area...and held it in with command strips from the 3m company. (this was on our 30rls Outback Sydney...I have not had time to do anything for the TM but probably will...may purchase from one of these companies...undecided at this time)
Here is one made for the Norcold refridgerator...the dealer also lists them for other makes of fridges:

The ads...state that it will not block the air flow...which is important.
