Which vent do I need?
Stupid question really, but I ve just bought a house with a bathroom window which contains what appears to be half of some sort of ventilator stuck in it. I ve done a bit of googling and it looks like it may be a vent-o-matic.
Now I want to replace the vent without breaking the window, but it s firmly stuck in there, and I cannot measure the exact aperture in order to ascertain which model I need to buy.
Can anyone tell me which model I need from the attached picture?
Sorry to post such a silly question.
