steel-clad door must be produced with an iron sheet-steel, minimum thickness 20/10 (2 mm);

the door frame must be fastened to the wall with at least 8 round iron pins with a diameter of 10 mm and at least 20 cm long;

the door must have stiffening bars;

the lock must control at least 10 bolts;

the safe lock must be protected by the door frame which must be applied on the hidden part of it;

the most modern safe lock is the lock with the Euro cylinder which includes lock block, European profile cylinder, steel shell and to have more protection, we recommend to install Fontana Kit Cover on your existing lock;

the lock without the Fontana Kit Cover is extremely subject to attacks and forcing with framing tubes used in scaffolding;

the lock keys must be duplicating controlled;

keys you buy must be sealed and must be open only when they are delivered;

the shell assembly and the choice of the roll length must be carried out by experts to avoid wrong and dangerous installations, for example when the shell juts out becoming too feeble and exposed to ill-intentioned people;

instead of a normal steel shell is better to install Fontana Kit Cover which prevents the access to the key-hole by unauthorized people;

Fontana Kit Cover is the first barrier between your private property and the outside world: you will wrong-foot ill-intentioned people preventing them from knowing what kind of lock you have;

The last recommendation which is the most important: ask professional experts to install the steel-clad door and safe locks. Mistrust scratch professionals even if they offer you lower prices: it is for your safety!
