Morning all! I need to build a couple new cabinets to go in over our new refrigerator. I will screw thru the face frames to the end panels but I'm concerned that that's not enough support for the weight that could land in those cabinets. The new cabinets will be 5"-6" short of the back wall, so I can't just run screws through the backs to the studs or a rail anchored to the back wall.

I have to believe that this is a common issue for cabinet installers, but I came up zilch for relevant results with google this morning. Can someone offer a technique to handle this situation?

Thanks!
