• GERDA is an additional securing lock suitable for all types of front doors /if someone tells you he cannot  mount GERDA on the door which you are ordering now, just deduct BGN 100.00 of his price – we guarantee the mounting later, or simply change the manufacturer./

• When heavy, expensive cash locks mounted on recklessly solid and expensive doors are opened as if with a key, the real choice at the moment is GERDA TITAN.

And yet, why GERDA TITAN?

•  4,000,000,000 combinations /the best lock cylinders reach up to 300,000 and the most expensive cash locks for doors reach no more than 1,000,000  /no error: 4 milliard/.
• This makes unlocking without a key impossible /There is no locksmith method invented for unlocking GERDA TITAN so keep a duplicate key in a safe box/.
• Titanium protection against drilling and cutting /use of titanium alloys for the lock tongues and the central cone for key input – it is hard to drill a cone even from a soft material/
• Key with volume latch function – have a look at the unique key – hollow /with an opening along the axis/, being cut from four sides, it enters the lock extremely precisely, and you will see why unauthorized copying is impossible. And the authorized copying is implemented only against the blue card GERDA certifying the ownership.
• Anti-burglary function from inside (You decide whether to allow or not opening from inside). Leaving the home in the morning and turning your GERDA key twice, you block opening with the thumbturn from inside. /And since burglars cannot break into your door, their only chance is through the window or through the common terrace of the neighbor./ GERDA, however, also protects the door from inside, so they will have to go back from where they have come.
• Attested by the British Standard Institution - London with Bs3621, Bs5872.
• Last but not least, prevention – upon planning of burglaries, the criminals leave out doors with the GERDA logo which is on the socket.
