WK3 hardware – anti-burglary. Available in the future.
The WK3 security class means that a window cannot be forced by use of simple force and a crowbar for at least 5 minutes. In order to achieve this, the best bolts must be used and spaced very closely apart – at least two in all corners or four for large windows and at least two on the side of each profile.
A class WK3 window has therefore a minimum of 16 security points. Single-bolt or mushroom hardware is rarely used in this class. Most often it consists of a number bolts operating as a complex self-locking mechanism. There are several in-house solutions on the market. In order to increase the level of protection offered by class WK3 windows, it is also recommended to use a counter-closing central mechanism, consisting of two locking mushroom rollers.
The rollers are anchored on both sides of the anti-burglary hook mounted in the frame and operate on the principle of opposing force – when attempts are made to lever one roller, the second one tightens on its hook with the exact same the force that is applied to the former.
