I need two plastic hinges for my shower door. It is a pivot door with 1 hinge on top and one on bottom. The hinges slide into the door and are held in place by one screw each. The part where the screw goes in is thicker than the bottom part that acts as the hinge.
Know where I can find these parts?

I have the exact same question. Is there a web site I can buy these hinges from?
