| Question:
Hi Tenmat Firefly ventilation valve. Can you please confirm that the stated dimension 100, 125 etc refers to the diameter of ducting that it fits - not the outside diameter of the device? Thank you |
Answer from Rawlins’ Technical Team:
Yes the listed size is the diameter of the extract and supply pipework, not the total diameter of the item. | |
