Gretsch-Unitas GmbH announced the presentation of a designer window with RC3 burglar resistance and a new UNI-JET SCF concealed hinge system at FENSTERBAU FRONTALE 2026.
The UNI-JET SCF concealed hinges for systems with a 30 mm rebate depth can support loads of up to 150 kg without additional load relief and up to 180 kg with it in windows and balcony doors. At the same time, the system enables the production of wider sashes without installing an opening restrictor.
Installation has also been simplified: the installer can hang the sash even when the corner drive is closed. In addition, the new system is compatible with previous versions of the hinge system, which facilitates the retrofitting of already installed units.
The concealed hardware has been tested to burglar resistance classes up to RC3. This allows it to be used in projects where both design and an increased level of security are important.
