FERNO external doors are produced in all designs and shapes according to the client’s individual concept.
As a standard, our windows are equipped with NT hardware produced by ROTO Company. It allows for easy product service and ensures comfortable exploitation. Additionally, it is possible to increase safety measures by applying special bolting rolls or anti-break-in catches.
Available variants of bolting rolls:
- bolting rolls E
- bolting rolls P: anti-break-in interlocking mushroom rolls
- bolting rolls V: anti-break-in interlocking mushroom rolls with vertical adjustment +/- 0.8
In versions where design is a priority we recommend ROTO NT Designo hardware – the hinge-side is concealed, therefore nothing disrupts the impression of perfect appearance.
