This is made of aluminium and stainless steel. All fixing parts will be concealed into the profile groove after closing. Only the beautiful column with anodized finish remains outside. The clamping mounting mechanism needs no screws for installation and adjustment. The key feature of the hinge is that the adjusting structures are designed on fixing parts of the hinge, saving more space inside the hinge column. Therefore, the hing spindle, the key part for load capacity, increased its diameter from 10mm to 12mm. Appearance will not be changed because of adjustment.
