My contractors assembled and hanged these cabinets on the wall. I right away noticed that doors were not straight, they were closing at an angle. I made sure all screws were fasted, but only later I realized that
top part and lower part of the cabinet were not attached to the horizontal beam inside the cabinet.
Basically the horizontal wood beam was fastened securely to the wall, but the walls of the cabinets were not securely screwed to the wood beam itself. That's the way the cabinets were designed. I had to add couple of metal angles to prop up the horizontal walls and secure them in place.........
