The Revolutionary Concealed Hinge System

The concealed hinge you don't need to hide! 

There is no other hinge system in the world that provides the same solutions as TECTUS® from Simonswerk.

Made in Germany, TECTUS® is the most comprehensive concealed hinge system for premium flush doors. With features such as easy adjustment across 3-Dimensions, TECTUS® hinges bring an unparalleled level of performance, precision and control and have solved issues over what have previously been a difficult to build and maintain. 

For architects and designers alike, choosing TECTUS® can make the difference between realising your vision and having it remain just a vision.

When interior designers spend time detailing an "invisible" door, they can go through endless rounds of picking the right veneer to match the grain exactly, wanting to simply keep clean and dead-even gaps around their door panels. As TECTUS® is adjustable in 3-dimensions, large and heavy doors can be quickly installed, saving money for the millworker and installer and insuring it all looks precise in the end. 

In reality, for detail-driven designers, nothing is ever really completely invisible. At the very least, when you open that door, the hinge better match the finish of the hardware on the rest of the project giving a professional overall effect. Simonswerk offers the TECTUS® hinges in a wide range of premium quality finishes to do just that.

For example the SIMONSWERK original Metallic Bronze finish is now joined by three new bronzes to complement any interior themes.
