The right lock
"Retrofit mushroom head lock" – according to the clear, official recommendation of the police, which insurance companies also underscore. After all, burglars mostly try to break in by way of the most vulnerable weak point: the window. Simple window fittings without a mushroom head lock are then the weakest link in the security chain by far.
Therefore, not only is the best armor glass imperative for burglary protection but a secure window fitting with a mushroom head lock, too. This mushroom head lock is basically very simple: It consists of the so-called "mushroom pin" and the locking part that are firmly connected together when the window is closed. And thus protects so effectively against prying open; at least the time delay is important, which makes the burglary impossible in most cases.
Generally speaking, windows only have standard "roller pins". For this reason, retrofitting with mushroom pins is a very frequent as well as stringent requirement for a rock solid security concept. Incidentally, several mushroom head locks are used for larger windows.
"Mushroom head lock"? "Mushroom pin"? Retrofitting is very easy, even if the terms are rather complicated. We will be glad to explain everything to you in detail – if you wish.
