The Sugatsune HES range offers concealed hinges for a variety of interior door types.  They provide a seamless and aesthetically pleasing appearance, where neither the pin nor the hinge is visible from either the front or the back when the door is closed.

Range of hinges available to suit doors weighing up to 65kg - choose your hinges based on your door weight and dimensions. Three-way adjustment provides precise alignment during installation.

Important notes:

  • Doors are not supplied
  • Door manufacture and finishing is by others
  • Correct hinge size selection is essential for performance

The hinges divide into two parts for simplified door hanging, and multi-directional adjustment enables fine tuning after installation to ensure perfect alignment.

Sustainability & environmental approach

Environmental considerations include:

We work with Sugatsune for projects that demand:

  • Dependable performance
