ABSTRACT:
There is disclosed an all plastic hinge for hanging conventionally sized doors for buildings and the like. Means are provided to prevent the pin from rising out of the passage afforded by the hinge halves by establishing a preferred direction of pin movement in the pin inserting direction. An enlargement in the pin receiving passage is created by differentially shrinking the knuckle surrounding the passage during the process of manufacture.
