I am making some kitchen cabinets (sort of a pantry off of the main kitchen) which will consist of 3 cabinets that are 42" x 20" x 15 - 3/4 ply. This is my dilemma, I was thinking using 1/2" backing. I searched on this and it has been mentioned but those were for smaller cabinets.
Should I use 3/4 for the back or use cleats with 1/4 back to reduce overall weight?
Price is not a factor as it would be minimal - just strength. Also the lower part of the cabinets will have coat hooks which will add to the weight they need to support.
