Hi Glen,
I've used the metal pinned hinge quite a lot in years past. They have their own installation requirements to be sure. I've mostly settled in to using Sig easy hinges. (CA hinges) Not because they are better, just easier. Although I don't recall ever having had a failure with them.
We've received our first blast of about 6" with another 14" scheduled today and tomorrow. Did you ever locate that blasted snow shovel?
Dave
