Maximum Clearance, Maximum Concealment. The Ultimate Hinge for Flushed Paneling and Molded Doorways. The HES3D-W190 is the pinnacle of the Sugatsune concealed hinge line, specifically engineered to accommodate the deep setbacks required by modern architectural trends, such as thick cladding, door paneling, or decorative molding. Its Wide-Throw arm ensures that even heavily finished doors open a full 180° and clear the frame without binding. This combination of innovation and robust capacity makes it the superior choice for high-end, heavy door applications where safety and aesthetics cannot be compromised.
