Our Verona Secustik® window handles contain a jamming-device which provides integrated security. This makes it more difficult to move the window fitting unlawfully from outside. It works by a coupling element acting as a sort of mechanical diode. This allows for normal use of the window handle from inside, but jams the handle if anyone tries to turn it from outside by way of the fitting.
As the handle is turned through 180 degrees from the closed position to the tilt position, the jamming-device makes a series of clicks – proof of the built-in security you can hear.
There are many different profile systems available for aluminium, wood and PVC windows, and this stems in no small part from energy saving requirements and safety concerns, as well as design considerations. What is more, these systems also require compatible spindle lengths.
It follows that a range of window handles with different spindle lengths must be held in stock. This is inconvenient and leads to considerable additional logistical and administrative costs.
A single window handle for a range of window profiles. With VarioFit® for window handles, you'll always have the right spindle length for a variety of window profiles already in stock.
This is because the length of the adjustable spindle in the window handle adapts to the depth of the individual window profile, which is enabled by means of a pressure spring fitted on the spindle in the inside of the window handle. Thanks to the spring mechanism, the spindle is pressed smoothly into the square recess of the gear follower, ensuring a perfect fit.
The integrated Secustik® technology makes it difficult to twist the spindle and, consequently, move the window fitting from outside.
Compared to the current window handles with fixed spindle lengths, the Secustik® Verona window handle with VarioFit® reduces the number of variants considerably. The associated cost saving potential from the reduction in complexity is clear to see. It goes without saying that the new Secustik® window handle with VarioFit® is tested to RAL, and HOPPE has extended its 10-year operational guarantee on mechanical function to it, too.
