A flat in an old building is a dream come true for many people. Unfortunately, however, they are often inadequately protected against burglars. Especially because retrofitting security features to the ornate, high doors is usually difficult to implement. If you still want to protect the entrance door to your old flat better, you can rely on this door rod lock. Locking with this door rod lock takes place simultaneously at the top and bottom. Individual adjustments can be made thanks to the adjustable design of the lock. The hollow bolt technology with hardened saw protection plugs and a solid metal housing ensure greater security. The standard version of the lock is suitable for door heights of up to 2.75 metres; an extended rod set of 2x2 metres is available for higher doors up to 4 metres. - VdS-approved in conjunction with VdS class A or higher approved door cylinder - Proven hollow bolt technology with hardened saw protection plugs - Incl.
