The windows and doors are the main targets of burglars who want to get into the house. Safety against burglary has always been one of our most important aims, which is accomplished in highly constructive safety.

Our hopper-opening system provides high safety even in basic version. At the bottom edge of the wing there is a fixing catch with a knob which closes in a hopper bearing.

Roto NT can be operated comfortably and enables to apply electronic control and safety elements.

Fixing catch

Setting, fixing and safety are in only one element. All of the three variations can be characterised with optimised movement and easy setting. The same screw position enables to change the standard closing elements into safety closing elements in a simple and quick way
( in case of 13 mm ironwork system in the middle).

One of the examples of comprehensive comfort elements is the draught assurance integrated at the scissors. It keeps the window in a hopper position. The window shut by draught will not cause any more harm. Besides this the hopper slit can be set to 80 mm and 140 mm..
