Additional window security lock with convenient two-stage locking.
Your windows and French windows made of aluminium, wood or plastic can be reliably and clearly protected from uninvited guests with this security device. The fuse closes in two stages. Stage 1, protection of persons inside, can be achieved by lightly pressing in the locking bolt. You can then open the additional security lock without a key. Level 2 is the total lock. By pushing the bolt in completely, the fuse can now only be opened with one of the two keys supplied. In this state, it can withstand a pressure of over one tonne. The additional security lock is suitable for windows and French doors with a rebate thickness of up to 25 millimetres.
