Anyone else in this situation? Anyone got a solution?
Yes I had this on the beer fridge at the lake.
I got a wooden slat cut it to length and pre-drilled holes through the support brackets and the slat. Then installed it with a couple screws.
I also gave it a couple coats of paint before installing just so it would be easy to clean.
If you wanted to get real fancy you could use an aluminum bar and the drill and tap the ends.
Are there a "universal" replacement?
Not that I know of.
