Abstract: A universal hinge structure includes a hinge part attachable to a frame and another hinge part attachable to a pivotable closure which is to be mounted in the frame. At least one of the hinge parts includes a cylindrical body having an adjustment screw extending therethrough and protruding into either the frame or the closure member. The adjustment screw is restrained by a locking pin so that it can not move axially relative to the body. The adjustment screws is threaded so that rotation of the screw in the frame or movable member adjusts the pivot axis of the hinge structure relative to the frame. Embodiments for various frame and closure member materials are disclosed.
