Window and door retrofit bars are one of the best solutions against burglars.

Many models at different prices are offered in the market. We checked all the bolts, we could not satisfy a model. The previously offered bars have a number of disadvantages:

- The bars are large and greatly alter the view of the windows and doors
- They are awkward to handle, often additional keys are needed
- Windows can only be tilted if the bolt is equipped for this purpose and the bolt must be released before tilting
- The latches can not be connected to existing alarm sensors for a mechatronic fuse

What bothered us the most:

Large holes must be drilled in the visible area of the frames and windows / doors. If you live for rent, this is impossible without the permission of the landlord. And if you move, you can not dismantle the extra fuse and take it with you, otherwise ugly holes will be visible.

These disadvantages have been changed by a completely new development of the security bars. Patent protected and mountable within a few minutes without technical expertise.

This means for you:

A window door latch for retrofitting without holes in the visible area of windows and doors.
