Thanks for the link Darrell. The hinge I'm looking for is more heavy duty and mounts like a conventional metal piano hinge.
I recently had an interesting/bizarre experience ordering from McMaster Carr.
I'm a Canadian resident and ordered, 10 SS screws - 2" x 1/4-28 flat head - for mail delivery to my mail and parcel receiving office in Bellingham WA - but they canceled the order before shipping. Pasted below is the exact response I received from the sales manager.
We understand that you have asked us to ship your order to a U.S. address,
but we also have reason to believe that the order will ultimately be
exported. Unfortunately, we will not be able to accept your order. You
may be able to find an alternate supplier of a similar product by
searching the supplier database at www.thomasnet.com
or by conducting a
general search on the Internet. Please accept our apologies.
