We have those in the USA too there not that common residential wise but there very common for commercial buildings where they have water faucet that they don't want people to mess with.

Great, I think this should work here in Finland.

Thanks for posting the skp file, this way we can adapt it to whatever faucet we may need it and save the great handle design. I am putting a logo on top of mine.

Tusen takk for en greit og veldig brukelig ting! :)

Thanks, I lost that key, just what I needed.
