The whole of the hinge barrel may be tempered or a tempered ring 2 may be used at the end of the barrel. When a tempered ring 2 is used it may; have teeth 3 driven into the main part of the barrel 1 or it may have teeth engaging complementary teeth on the barrel in which case the position in which the hinge is held may be adjusted. The pin 5 may pass through a longitudinal slot in the pivot pin to prevent it from rotating with the barrel 1. |
