4-Degree Safety Double Opening System

The statistics show that hundreds of thousands of theft cases are recorded every year and a house is robbed almost every 2-3 minutes.  

EN 1627 - 1630 standards describe the hand tools and application methods used in theft resistance class tests. The conclusion article that states “According to the tests, if the hardware is equipped with special cork pins and counterparts at a minimum of 4 points, it may be possible for the window or the door to pass the theft resistance tests (RC1/RC2/.)” was taken into consideration for the relevant standard, and it was decided to use Double Opening accessories with a minimum 4° Safety class.
