A perfect fit, a powerful and durable lock and a strong espagnolette that can be operated easily are the things that keep doors permanently tightly shut.
On our Roto Safe combination locks, a combination of a bolt and what is currently the strongest power wedge available on the market joint forces impressively to achieve this: The power wedge engages first during the locking operation, followed by the bolt. What then follows is pure living comfort: no draughts, no noise, no heat or cold, no unpleasant smells – and the improved emission levels also ease the pressure on the wallet.
The highest gasket compression for excellent tightness
Highly effective for maximum energy efficiency and therefore lower energy costs. The result is ideal conditions for complying with all statutory regulations for emissions reduction and thermal insulation in buildings
Constantly high gasket compression prevents the door from warping subsequently – even slightly warped doors still close tightly and securely
The Roto Safe lock generation 600 is not only extraordinarily strong, it is also especially smooth and convenient to operate thanks to the optimised transfer of power from the cylinder or lever handle to the lock. A low-noise whisper latch is also integrated as standard so that the door closes quietly.
