Abstract
An adjustable hinge assembly is provided with three dimensional adjustment along X, Y and Z axes. The hinge assembly includes a first leaf mounted to a door or window frame and a second leaf mounted to the door or window. The first and second leaves are pivotally coupled via aligned knuckles for adjustment along the Z axis. The second leaf includes a plate slidably received in a housing. The plate is adjustable along X and Y axes relative to the housing. Adjustments on the X, Y and Z axes can be quickly and easily made using an Allen wrench.
