The steel band is better. Preloads the stress point. The problem is they are basically pot metal. To make the hinges self cleaning half the metal is missing where the pin goes though so there’s very little cross sectional area.

Then, rather than a pulley to change the direction (pull out = lift up), they chose to use a gear and lever that greatly multiplies the force on that hinge point.

So: reinforcing the brittle metal hinge with tough ductile steel makes it far stronger than new.

JB would actually be stronger than new and possibly be a forever fix but you’ll only get a couple mm² cross section and no preload.

Preload and much of the every use stress still compressing not tension.
