An elongated single- or double-acting hinge is described wherein extruded hinge column members and hinge pivot ring members of identical or substantially identical cross-sectional shape are coaxially supported in registering and mutually journaled relation on a common center rod. Door attachment bracket members extending along one or both sides of the hinge and affixed to a plurality of the pivot rings interspaced by one or more hinge column members permits swinging of a door secured to an attachment bracket with respect to the hinge column member or members and/or the center rod. |
