4T Tris closures for sliding doors and windows
A TRIS system may now be locked and opened also from the outside. A new patent, out in front once again. Yet more security.

Thanks to the TRIS system developed by us any sliding window may now be locked and opened also from the outside (only with the EUROPA closing system).
"TRIS" is a system patented by MEDAL which makes it possible to use from 3 to 4 closing points on sliding windows. This unique system also makes it possible to fit a cremone bolt on the main inner window (TRIS opera VIP, with versions and without key) and a double lock closing on the second window (TRIS EUROPA, with versions and without key), formerly impossible on sliding windows.

With the use of specific adapters, the "TRIS" system can be fitted to the majority of sliding window sections currently on the market, as shown in the cross-sections illustrated here.

    SIMPLE TO FIT just a few quick and simple operations, since all the components are designed to adapt to the sections perfectly, reducing the number of screws needed.>
  • STURDY a secure system, consisting of sections and accessories that ensure a rigid structure
  • TWO APPLICATION POSSIBILITIES The system is suitable for the mounting of an OPERA cremone bolt (a refined product of exquisite design that adds a touch of prestige to any ambience), or for a concealed solution if casement-overlapping is preferred.
  • FUNCTIONAL immediately appreciable thanks to the functioning precision with firm yet silent opening and closing.
  • INVISIBLE all the connecting components are enclosed inside the sections. Even when the window is open, the system is invisible.
