The Offset locking band is used in conjunction with 15/30/45 degree bends. It replaces the standard locking bands to strengthen the joints where long offsets are required to increase stability. This installation method allows a maximum of 250mm length (012) to be used be between the bends with no additional support required after the offset, if a longer offset is required provision for another wall band or support is needed after the offset.
The offset locking band also allows the offset flue to be fitted free standing up to a maximum distance of 1.5m from the last support (the wall band must have a strong fixings)
