Our Roto NT hardware boasts a high level of basic security even in the basic version and so provides greater burglary protection right from the outset.
You can easily integrate additional mechanical and electrical security and control elements to suit your individual needs – for maximum security and protection against break-ins, fire, gas and water.
The basic Roto NT lock concept consists of the simple retrofitting of centre locks with security cams and security strikers:
The following locking cam variants are available, with the security locking cams with mushroom head providing a particularly high level of security in conjunction with security strikers:
Thanks to a large stroke of 36 mm (optimum striker entry depth), the cam can engage securely into the striker even when production tolerances are high.
The two-dimensional cam collar guide also minimises material abrasion between the faceplate profile and the movable cam.
The reverse-action centre lock provides effective protection against attempts to displace the window by means of violent, lateral jemmying
For maximum security and protection against break-ins on windows and on balcony and terrace doors, we offer you special steel hooks from the Roto NT modular system that attain the same standard of security as on solid building doors.
In the case of the Secustik® window handle on the other hand, a special mechanism prevents the forced manipulation of the handle from the outside. This is the most attractive type of security on the window as it cannot be seen.
Our window hardware with Tilt-First technology – the intelligent security mechanism for (children's) security windows with the “Tilt before Turn” window handle – is ideal for use in children's rooms and public buildings (particularly kindergartens and schools). This improves security and at the same time permits safe ventilation in the tilted position.
Where security requirements are very strict, we recommend supplementing mechanical security with electronic security:
