I am getting ready to hang my upper shop cabinets. Below is a sketch of the wall and its details. Basically I have 1/2" drywall nailed to 1 1/2" thick furring strips which are screwed through foam board to the concrete block with Tapcon screws. My question is will 3" truss head cabinet mounting screw through the cabinet back and drywall into the 1 1/2" furring strips hold up the cabinets?
There are three cabinets, one is 37" long and will be screwed into two of the furring strips with screws at the top and bottom. The other two cabinets will be joined together (screwed through the face frame to each other) and end up 58" long screwed into the furring strips with a screw at the top and the bottom.
Is this adequate to hold them and their contents securely? My other option would be to use 4 1/2 Tapcon screws through the cabinets into the block wall. The 4 1/2" screws would penetrate 1/2" into the block. Or should I use 5" Tapcon screws?
Here is a cross section of the wall.
