With a security pin you can protect outward opening windows and doors against burglary. By placing the pin, you upgrade standard hinges to safety hinges. The security pin consists of a bush and a pin that you can easily mount directly opposite each other in the door or window frame. When burglars destroy the hinge pins, it is no longer possible to open the window or door to the outside. It is not without reason that the Nemef security pin carries the Police Quality Certificate for Safe Living and the SKG quality certificate.
