Our rule is: one lock per metre. For a regular single casement window, this means that – depending on the size and quality of the window – you should expect up to three locks to be protected against break-in as comprehensively as possible.
It is our top priority that our additional window locks protect you and your family from break-in. This is why, among other things, many additional security locks can withstand a ton of resistance. In addition, we have made sure that they are easy to operate and can be matched to your windows in terms of colour and material. Therefore, we offer you many variants to choose from, whether you want brown locks for wooden windows or white or silver ones for plastic windows, or other options.
We’re certain: We have the right additional security lock for your single casement windows!
