Casement window hinge isn't working anymore. The black plastic piece is broken so it won't slide over the screws holding the bracket. The only markings I can identify on the hinge are Truth and 40941. Do you have a replacement part for that?

Sure, we carry many different hinges. The number you gave us is often associated with our 36-013-10. I recommend carefully looking over our pictures and measurements to confirm that this is what you have.
