Retrofitting mushroom head lock

Hello,

our nearly 10-year-old double-glazed wooden windows with fittings from Roto partly have mushroom cams and partly normal cylindrical parts in the locks. The strike plates in the frame are apparently already designed for mushroom cams everywhere.
Can the normal cylindrical locks simply be replaced with mushroom cams, or do the complete fittings need to be changed? I have not seen the mushroom cams as individual parts anywhere.
If this is a simple measure, I would consider it to increase burglary security. I am aware that the rest of the house has to match, and I will seek advice from the police on this if possible.

Regards
Michael

Hello Michael,

You need to replace individual fitting parts. Depending on the window size, this can be about 7-10 parts, which together form the entire fitting. You can either replace all or only individual parts (e.g., scissors, corner transmission, gearbox...). It is not possible to replace only the standard roller pins with mushroom heads.

Thank you Peter,

that helps me. Sounds like a bigger effort.

It's actually okay. You can unscrew all the parts without much effort and screw on the new ones. What's more important here is clearly that you buy the right fittings for the window. More mushroom heads don't matter from an insurance perspective, so basically all floor-to-ceiling windows make sense (so the patio doors) and the windows where you can enter with special protection. No one breaks in through the small bathroom window that's clearly visible from the street.
