This is a professional-grade concealed hinge model featuring a contemporary design with rounded ends. The central knuckle prominent displays the “G.D.O.” brand logo, and the model number is marked on one of the leaves. A key functional feature of this hinge is the use of removable cover plates on both the door and frame sections. These plates conceal adjustment screws, indicating that the hinge offers 3D adjustability (vertical, horizontal, and depth), allowing for precise alignment of the door during installation for perfect operation.
