Door fitting KKT512


Protect your flat door against burglars with this door fitting.

On flat doors, the door cylinder often protrudes slightly. A weak point that burglars exploit to break into homes without permission. Your flat door can also fall victim to this method. Unless you secure them with a reliable door fitting. This compact door hardware is suitable for universal use on flat doors with a door thickness of 37 to 47 millimetres, regardless of whether they are right-hand or left-hand closing. The layered construction of several steel plates makes it particularly safe. A steel insert in the handle provides high tear-off protection. Hardened and tempered special screws and extra-long steel cams secure against violent break-off attempts.

Door fittings

Any door that is not professionally secured can be immediately identified by burglars as an easy target: The cylinder protrudes a long way and often the fittings can simply be unscrewed. This makes breaking in easy, and not just for professionals. An ABUS security door fitting protects both mortise locks and door cylinders against being broken or pulled off. Look for the DIN, TÜV and VdS seals of approval. They are proof of maximum security. ...
