Door catch with small lever

We didn’t even know that we had something like that.. We didn’t know it either. Our neighbor was the first to point it out to us.. :D Now we find it practical.

We have a bargain like that here, same manufacturer. You have a trade list after all. Couldn't you ask the window and door maker if he can get one?
Best regards

Hello Gabriele, you're right, I hadn't thought of that at all. I had contacted Kerbotherm by email, but hadn't thought of the executing company. Thanks for the tip :)

So, I received an email from Kebotherm, the daily trap including travel and installation including VAT for an incredible 430€. Or without installation, just shipping for a mere 160€.
It really knocked me off my feet.... At least I now know which part I need.... :D

Another question for the pros:

The door opener is called 118E530 and apparently comes with the additions D11 and A71, which stand for two different voltages. Since I don’t have power for it anyway and don’t need it, I can take the cheaper version, right, or are there any objections?

Thanks!

Yes, take the cheaper one.

Google also offers "Tagesfallen" for retrofitting at a low cost.. No idea about the quality.. but maybe it's worth researching here again..
