Living comfort is important to end customers. Ventilation as required in various temperatures and (at the same time) heat energy savings are especially important.

Our Roto NT hardware system is based on a proven concept which, thanks to a very wide range of accessories, covers practically all the customers’ needs and meets individual demands for making day-to-day living more pleasant.

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:

Due to the identical length, standard strikers can be easily and rapidly replaced with security strikers

All strikers are interchangeable without having to change the central locking system

All locking cam versions can be combined with the same strikers

All strikers have the same screwing axis, which means that no additional drilling is needed and no screw holes are visible

On the underside of the sash, the hardware is already fitted with a mushroom cam, that engages in the associated Tilt&Turn striker. This means that fewer additional components are needed for upgrading

Roto NT is tested and certified in accordance with DIN 18104-2 as burglar-inhibiting retrofit hardware

Roto NT is tested and certified in accordance with DIN EN 1627-1630 up to resistance class RC 3 for PVC profiles and resistance class RC 2 / RC 2N for timber profiles

No visible security components in comparison with conventional retrofit products

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:

Locking cam E: Adjustable gasket compression +/- 0.31 inch

Locking cam P: Security mushroom cam with adjustable gasket compression +/- 0.31 inch

Locking cam V: Security mushroom cam with adjustable height +/- 0.31 inch and adjustable gasket compression +/- 0.31 inch

Thanks to a large stroke of 1.14 inch (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.

Security handles in the lockable version from our classical RotoLine and modern RotoSwing window handles range provide security against attempts to displace all the hardware from the outside.

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 guarantees security and at the same time permits safe ventilation in the tilted position.

The window sash is locked in the tilted position when the handle is in the horizontal position

The lockable handle with the profile cylinder thereby prevents the possibility of changing from tilting to turning with the handle in the horizontal position in order to fully open the window

The window handle can only be turned up further with the handle key

If the window is to be used for a different purpose later, the safeguard can be removed relatively easily by changing the hardware.

Our hardware is used in windows throughout the world, which means that it must be able to withstand a very wide range of climate conditions and environmental influences.

In order to do justice to our high quality claims in this respect, in addition to strict quality checks in development and production we also particularly depend on optimum component quality, and this enables us to provide a 10-year functional warranty on all Roto NT components.
