Tall cabinet without top panel?

Hi everyone,

if you place a built-in oven in the following cabinet, what is then used as the top panel?
With the 195cm high tall cabinet body, the ceiling is included but not here?
Do you simply put a countertop on it? How do you attach it? Sorry for the dumb questions.

THANK YOU!

Hello,

"Incl. ventilation grille. Complement with separately available worktop." The narrow ventilation grille, which can be seen in the picture, is inserted into the worktop at the top. The worktop is screwed to the braces.

Yes, it is intended to mount a countertop on it, the metal bars at the top have holes, through which the countertop can be screwed to the carcass.
