The additional door lock withstands a pressure of one ton while still allowing contact with the outside. Do you want secure doors but also the ability to know who is ringing your bell? This additional door lock meets these criteria. The lock features strong wall anchoring with heavy-duty anchors and can withstand a pressure of one ton. The sturdy oval bolt made of solid steel also protects your door from attempted break-ins. A hardened steel shackle allows you to open your door slightly while it is locked, for example, to receive mail. For even more security, the lock can be combined with the pull protection plate PZS70. It is operated from the outside with a key and from the inside with a turn knob.
