Unequal Height Piano Hinge.

[MEXICOWANDERER]

I can't find them because I don't know the proper name for them.

A quarter-inch thick square of transparent polycarbonate
To read gauges, switches, and gauges beneath.

The Lexan hinges to a much larger surface lid read above.
NO clean edges on the box to have a 90-degree natural surface, the Lexan has to lay flat and open with a hinge

Got ideas?
Thanks.

Maybe it's a flush mount piano hinge.

Search on Amazon for offset hinge or offset piano hinge.

Not. Sure if that’s what your looking for. I looked on Rockler.com and didn’t see as many as Amazon had.

I think they're called offset hinges but I've never seen offset piano hinges. i used to put the offset that I wanted into piano hinges with a sheet metal brake. Craig
