Pop-Top Ladder Hinge (pair)

This is a direct replacement for the plastic hinge shown on the left of the first photo. It is printed in nylon and uses some metal parts for a stronger result than the original hinge.

Instead of a plastic hinge pin, it uses a much stronger stainless steel rod.

Instead of visible bolts, it hides those bolts for a neater finish.

The hinges are sold as a pair with instructions.
