Is this a test? it seems pretty clear to me. zoom into the pics. You can see that a screw in the wrong place has blown out the box. Who did it only that person will know.:slaphead:
The box has three screw holes, each tapped to accept an 8-32. I do remember that the knock outs on these boxes quickly snapped out and detached from the boxes as you can see in the pics. Normally, as you all know, these "cable grips" remain and put pressure on the romex. I'm thinking these boxes were overly brittle for whatever reason. I mailed the remains back to Cantex today to get their take on it. The thing that really bugs me the most is why the failures happened all in the same house when these boxes were used in many other installations. That leads me back to the sheetrock crew but that still doesn't account for the brittleness
