Roto Solid Concealed Silver Door HingeRoto Solid C, the concealed hinge for inward and outward opening entrance doors manufactured in aluminum, offers impressive functionality and ease of processing. The hinge is life tested to over 400,000 cycles and can be used to build entrance doors up to 140 kg (280 lbs.), and with a maximum opening angle of 110 degrees. For efficient fabrication time, the frame hinge and sash hinge are packaged separately.

Roto’s newest update to Solid C is the height adjustment module for inward opening doors. The smart slim design of the new module is tailored to the frame hinge and therefore blends even more seamlessly into the overall appearance of the door. The module is available in black and silver finishes.
