Additional security lock FTS15


First aid for your windows: This robust security device with combination lock provides additional break-in protection for your outward-opening windows.

All variants for FTS15
Make life difficult for burglars with our FTS15 window security lock.
The additional security lock in discreet white is suitable for wooden windows that open outwards. This makes it the ideal security solution for awnings and skylights. Included glazing bead protection for the outside of the window makes break-in attempts even more difficult. This way, the FTS15 can buy you valuable time to get help in case of an unwanted visit. With a pressure resistance of up to 600 kilograms, the security device also helps to ensure that your windows remain closed, even in the event of storms and violent external influences.
What's more, it does not need a key at all - a 4-digit, individually adjustable numerical code is sufficient for operation. This keeps your key ring slim and your home safe. The FTS15 is made from corrosion-resistant zinc. It is certified to meet class B standards according to the SS 3620:2017 standard, and meets ABUS security level 8 out of 10. With the help of our supplied drilling template, you can easily mount the fuse on the frame on the inside of the window. After that, it is immediately ready for use.
