This is a bracket used to stabilize one of the righthand shelves in my Samsung model RF27T5241SR refrigerator.

This fridge has two sets of shelves-- matching right and left-- which appear to be intended to be at the same height in a pair. However, I found it much more useful for fridge organization to set the right and left shelves at different heights; which is possible, but not as stable. Without the support from the left shelf connected, the righthand shelves can pivot off their back corners, come dislodges from the righthand wall, and potentially fall down! This little bracket serves as a brace/lock that adds a front frame corner, effectively eliminating the shelf's ability to rotate.

This bracket works perfectly for my needs, but is so specific to these shelves that I doubt many people will get use from it... I'm hoping this model will be inspiration for remixes and variants.

Mine is being held in place by an outdoor Command strip, which I'm guessing can handle the cold/temperature changes/contraction better. So far it's been in place for about a month with no issues.
