You are saying that the door was safe when it left the manufacture and left your hands and that of your seller, but the contractor installing it might be liable [should he/she have reasonably known that missing piece had to be there? Why would that take 18 months before it shattered? Contact the manufacturer and tell them what happened. They see liability claims all the time and hire attorneys to handle them. You can probably ride on the coattails of the maker of the door, as they will want to say it was safe when it left the seller's possession. It does not seem that you have any liability, but if a suit is filed you may be included by a cautious attorney who brings everyone in who might have any liability.
