I have a FR 3050s and there is a pantry next to the frig that is narrow and 26" deep. DW could never get at the items in the back. So a fix was needed. What I did was bought 6 shelf bin # 184842 from Global industries. These are 65/8"W x 235/8"L x 4"H. Now DW just slides the bin out and can get to the items in the back. (The shelf bins come in all sizes).
But that caused a slight problem as at time she would pull the whole shelf out off the mounts. The fix for that was easy. I just went to HD and got a piece of suspended ceiling L channel and cut pieces that when wall to wall and put them on the shelves. These hit against the front framework and stop the shelves from moving forward.

I tried to attached a few pictures of the setup but couldn't, but will keep trying.
