KOBLENZ KUBICA K6700 Concealed Hinge 111mm Satin Chrome 3D Adjustable 70kg Universal

Product Overview

The KOBLENZ KUBICA K6700 concealed hinge features a satin chrome finish and is designed for flush wooden doors, fire-rated doors, and frames made of wood, aluminum, or steel. Widely used by professional installers and furniture manufacturers, this hinge delivers a seamless door-to-frame visual plane and has been certified by Instituto Giordano, confirming quality and performance for demanding commercial projects.

The K6700 stands out for its full three-dimensional (3D) adjustment, allowing easy fine-tuning in height, depth, and lateral position with a single hex key, without removing the door leaf.
