Sure looks flimsy to me.
I'd go with a brass plate rather than this.
However, I roughed up the plastic hinge (you know they have silicon mold release as molded, right?) and filled the voids with 2 part epoxy. Seems firm enough but you have to remember, the plastic bottom strip is flimsy as well.
I'm still convinced the best way to avoid a catastrophic failure to the new door, like we experienced on the old, is to not store anything on the door.
Unfortunately, my better half disagrees (I'm waiting for another failure).
But, as I'm only the fixer, what do I know?
