How the attachments can be universal for both DN 50 and 70 diameters of balcony outlets?

Balcony outlets have a flare or an integrated flange of the outlet of the same design and diameter. Design of outlets differs according to the product only under the flare. It is for the reason of universality of all accessories.

What type of attachment shall I use if I have trowelled hydro-insulation that is in a level of the outlet flare?

For this type of hydro-insulation, TWNR BAL v50 (P) is determined, which may be mounted according to the height of screed and pavement.
