Well, first off, I do have 1/16" alum angle on my door opening and I did fit the door flat against that when I put the hinge on. There is a bike tire tube behind the hinge for weatherstripping.
I took off the D seal from Grant and tried some other that I had new in the pkg, it's about half the size-- can't remember the numbers right off.
Seems to work better but I might try a little something else too. The door is shutting better, I haven't cut for the door latch yet
We'll see. ..
Some things are way over my head !! ...but it keeps me looking UP!
