The Schiedel Adjustable Back Bracket 60-300mm for twin wall flue is a support component designed for use with a wall band, providing an adjustable 60-300mm range when positioning the flue system relative to the supporting wall. It is available for 130mm (5″) and 150mm (6″) internal flue diameters.
The adjustable format is useful where the wall band cannot be mounted immediately against the supporting surface. Its 60-300mm adjustment provides scope to set the required bracket position as part of the overall flue layout.
This component is listed within Schiedel’s twin wall flue support component ranges and is intended to form part of the structural support arrangement rather than the flue gas-carrying section itself.
The wider Schiedel ICS system uses a push-fit jointing arrangement secured by locking bands. The system construction uses laser-welded 316L stainless steel inner liners, 304 stainless steel outer casing and a 25mm Superwool insulation blanket. These are characteristics of the associated chimney system rather than the adjustable bracket itself.
Two internal flue diameter options are offered, allowing the bracket to be selected to suit either a 130mm (5″) or 150mm (6″) system.

Expert Insight
The key specification here is the 60-300mm adjustment range. This allows the wall band position to be adapted where the flue needs to stand further away from the supporting wall, rather than relying on a fixed-depth bracket. The correct diameter option should be selected to match the associated Schiedel twin wall flue system.
Suitability
This adjustable back bracket suits Schiedel twin wall flue installations requiring a wall-band support position between 60mm and 300mm, with versions available for 130mm and 150mm internal flue diameters.
Installation / Technical Notes
The bracket is designed for use with a wall band and provides a 60-300mm adjustment range. Select the appropriate version according to the internal flue diameter of the system: 130mm (5″) or 150mm (6″).
