Universal and safe: This door fitting protects right- or left-opening flat doors with a door thickness of 37 to 47 millimetres against break-in attempts.

All variants for 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.
