Protection against a pick-lock effraction
Protection against self-impression
Protection against drilling out
Ease of use
Ease of installation
The absence of lever rigid springs and existence of false grooves complicates the task of lock effraction by means of manipulation.
Sectional toothed hub covers the side ports and restricts picklocks’ access to the levers through the key hole (utility model patent No. 142635).
Patented hub protects against self-impression effraction (utility model patent No. 100538).
Internal and external armor plate, installed at the bolt shank (utility model patent No. 137899), protects against drilling out method.
The function of latch switch off from the handle in latch closed position (patent No. 142627) provides lock operation without lateral pressure at the shank. In closed position, lock latch remains in fixed position even when the handle is held down.
Smoothness and silent running of the crossbars are provided by means of gear and absence of levers’ rigid springs.
Window type levers provide easiness of key running when closing/opening the door, as well as exclude the possibility of slipping and “hang up”.
Holes for the fixation of the door handles by tightening screws through the lock provide ease of installation and reliability of handle operation.
Removable end plate allows installing the lock by means of insertion.
