Rc2n - Window fittings on the ground floor

Hello, according to the contract with a general contractor, windows are to be installed on the ground floor of my new building, which are to be equipped as follows: " Beschläge gemäß RC2N ". Visually, I cannot see any difference between the windows on the ground floor and the upper floors. What should I pay attention to in order to be able to detect a difference here? Thank you in advance for your answers!

Hello,
there are clearly more of these mushroom head locks installed. The frames are also anchored in the masonry with more screws.
The panes are the same, you won’t notice a difference there.
Are the windows already installed and you’re now looking for the differences? Or are you still selecting samples?

Best regards,

Andreas

The windows are already installed and significantly more mushroom head locks are not present.

Then they will have either installed the normal windows at the bottom or accidentally also RC2n at the top. Do you have pictures of the fittings?

So with us, the windows on the ground floor (RC2N) have 3 fully protruding mushroom heads. The otherwise identical windows on the upper floor have only one real mushroom head and otherwise only 2 non-protruding sliding things (no idea how to describe it). Similarly, the terrace door has 4 real mushroom heads and on top only 2 real and 2 "fake" ones.

I can take pictures tomorrow and publish them here. If you want, you can have a look at them.
