👉 The reinforced black structural locking band tightens and thus reinforces the joint between two elements of the black DPI flue in order to increase the stability and rigidity of the whole installation against wind loading on the flue where it exits the roof. It is recommended to use this type of band above 2 metres in height (free-standing flue).
⚠️ Bofill insulated twin-wall flue accessories may be compatible with other brands of flue provided they have the same internal / external dimensions.
