I came upon them by accident while waiting a half hour for the guy at HF to figure out how to cut the 3/4" hemp rope, but...
I see they come in a few cool standard lengths--24", 36" and 48". They LOOK like piano hinges, but they seemed a little flimsy compared to what I expected from the rigidity of a piano hinge. Granted, once secured to wood, maybe this is not an issue. Also, I think the material is zinc coated, so I don't know about weather durability either.
Just curious to know if these are an acceptable option, even if not the BEST option, in case I don't want to deal with any more packages getting delivered to the house--and getting yelled at even more by my wife.
