The connection where the opener arm attaches to the door is not as secure as I would like. It was fine, but a spring broke and things got quite stressed more than it should. It is no longer possible to get the bolts as tight as I would like into the door.
I am considering a steel plate on the outside and bolt it though the plate. That should function well enough. (Note per the instructions there is a steel angle as a brace under the opener arm on the inside of the door now. The door itself seems solid and everything is functioning OK.
I am also considering this as an opportunity to just replace my two doors with something a little nicer and with windows.
Any suggestions or comments?
