KTV Felt ventilation set/Ridge + adapter

The KTV roof vent can be used for ventilating roof structures and attic spaces as well as for ventilating sewer pipes. The KTV roof vent can be selected from 10 different models according to the roofing material. The selection principles are the same as for pass-through sets. A KTV roof vent contains a valve, pass-through, an underlay ring and fixing screws. It can also include an Ø 110/125 adapter, if needed. The set is also available with a flex pipe if the KTV roof vent is to be used for ventilating a sewer pipe.
