This additional lock makes a usual Abus-typical high-quality impression. The installation instructions are easy to understand and sophisticated technology. Whether it can permanently prevent a break-in attempt yet I dare to doubt. A ton pressing force may sound like a lot at first to, in terms of fixing the wing side with only 2 to 3 small screws and the fact that a lever pressure from1 ton can be quite easily erzeug by correspondingly large crowbar, such a lock should be in accordance with long Bearbeitungt also eventually crack. A deterrent effect, it is nevertheless delayed and a possible break-in attempt with safety. However, you should pay attention before buying, make sure that you have windows / patio doors with external hinges on the window frame. In my windows this is unfortunately not the case. The hinges are built here in the frame. This open and close the windows in the rotary motion with a slight swiveling making not possible to mount these locks. Because an assembly must take place exactly in the axis of the existing window hinges to allow an unrestricted opening and closing. Unfortunately, this goes, and that is also my criticism-point for only 3 star, not sufficiently clear from the item description. Finally, I've stupidly then ripped his finger to something unclean deburred rivets, falls with regard to this vote but rather by careless and home suffering. And if I'm doing already: The photos in this article show the description pushpin mainly with a white head. In fact this is, as shown only in Figure 4, fiery red and immediately catches the eye. Also in the product box itself the whole press pin is displayed in white.
