HOOK SYSTEM is the retractable door block designed and patented by our company in 2022. 

The materials used are selected to guarantee a long life to the accessory, the hook with a diameter of 12 millimeters and the small parts are made of stainless steel, while the PA6-6 nylon casing with glass fibers. 

The HOOK SYSTEM sash stopper can be installed on both windows and French doors and its installation is carried out in our factory with ad hoc processes, using computerized numerical control machinery.

 Among the advantages we highlight an easy and quick use, the absence of further accessories external to the window to be applied and installed on the walls, a quick installation. 

Hook System is an accessory that does not alter the aesthetics of the window and allows the end user to lock the sash in safety.
