how is it secured in the ceiling?
Thank you for your question.
The valve is fitted by unscrewing the back part off. This part is then fitted into the hole that has been cut and screwed to the plasterboard or ceiling the front part then screws back on.
The DUCMW104. Is this preferable to cheaper alternatives for high moisture environments? Will it start rusting after time? In the photo, it looks more off-white than white. Is that correct?
Can this connect straight to the female round to rectangular adapter (DUCVKC236)?
