Concealed Italian-made Otlav Invisacta 300 3-D hinges for interior doors are used in conjunction with aluminium decorative strips that hide adjusting and fixing screws; they give the hidden hinges a refined look.
A distinctive feature of this hinge is 7 connecting elements, which provide high load capacity, minimal friction and smooth motion.
The opening angle is 180 degrees. The hinge has been tested for 200,000 opening cycles.
