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

Even when the window is open,
the system is invisible.
