Roto window and door handles are tested for their long-term proper operation in a large number of tests. Long-term functional tests which realistically simulate the demanding “everyday life” of window handles are carried out depending on the requirements.

Roto provides a 10-year performance warranty that exceeds RAL requirements as long as the necessary assembly and maintenance guidelines are observed

The Secustik® mechanism

Secustik® window handles contain a patented blocking mechanism for integrated basic safety. It prevents the window hardware from unauthorized displacement from the outside. A swivel clutch between handle und spindle functions as a “mechanical diode”. It allows the window handle to be operated normally from the inside, but it blocks the handle if anyone attempts to manipulate the window handle from the outside via the hardware. The handles thereby fulfil the requirements specified in A-JH RAL-R 607/13.

When Secustik® handles are turned by 180° from the locking position to the tilt position, the self-locking locking mechanism engages in various handle positions with a discreet click. That is how you can recognize this outstanding security factor.
