Pair of 100mm diameter pipe couplings for ducting

Two couplings for ducting, for 100mm diameter pipe. For F.lli Lerda brand fireplaces.

All inserts in the F.lli Lerda range are designed for one or two ducts. This type of installation allows the hot air produced by the fireplace to be conveyed not only to the front side and therefore into the room where the insert is positioned, but also into adjacent rooms. The manufacturer guarantees good performance for ducts of up to 5 meters in length and made without elbow bends.

This pair of coupling sockets will allow you to connect the ducting pipes (flexible aluminum or steel covered with mineral wool) to the top of the fireplace, where there are the two arrangements on the sides of the fume exhaust
