An investigation was conducted using interviews and examining three photos of the unit, lag bolts, and wall where it had been attached.It appears that the top bolt came out of the wall and the bottom bolt was bent from the weight of the unit.A root cause could not be determined; however, it appears that the unit had been moved since the initial installation.The re-install may have diminished the wall stud integrity to support the unit.Sales of the expert dc were discontinued on june 24, 2016.This concludes the investigation.
