Easy installation, effective protection!

As already mentioned in the article description, this castle of the fuse is inward-opening windows and doors. For operation: In closing mechanism (part of the keyhole, is mounted on the window frame) is a steel bolt, which locks on the outer frame when closing in the abutment. Close happens without a key, opening.

The installation is very simple and requires only one effort in terms of pre-drilling in the exterior and window frames - this, however, make sure that you do not anbohrt the window mechanics :-). The height adjustment between the two frames designed easily by spacers. All in all it took me a good 30 minutes. The gland is very stable and offers high strength. The safety factor is specified by ABUS 5 (scale goes to 10), and thus represents an average. I believe a break-up of the window is only possible with considerable violence and corresponding damage. Who still wants to go one size safe, which can - instead of another castle with higher factor - installing two of these castles left and right.

Conclusion: Relatively inexpensive and easy to install additional security.
