The Schiedel ICID Twin Wall Locking Band for Bends is a structural locking component designed specifically for ICID bends. It secures the system’s twist-lock bayonet jointing arrangement and is available for 125mm (5″) and 150mm (6″) internal flue diameters.
Unlike the standard ICID locking band used across general system joints, this component is intended for bends within the twin wall chimney system. Its role is to provide the locking mechanism around the bend connection, securing the twist-lock joint once the adjoining components have been assembled.
The Schiedel ICID system uses a twist-lock bayonet jointing method, with this structural locking band forming part of the mechanical connection at the bend. The correct band size should therefore be selected to correspond with the internal diameter of the ICID flue being installed.
Two versions are available: 125mm (5″) and 150mm (6″). This makes the component suitable for the corresponding bend sizes within those ICID twin wall chimney systems.
The wider ICID Plus system is designed with a load-bearing outer case while the inner liner remains able to expand independently. This construction allows thermal expansion to be accommodated within the individual joints of the chimney system.

Expert Insight
This is the bend-specific locking band within the ICID system rather than the standard locking band used for general joints. Its function is to secure the twist-lock bayonet connection around an ICID bend, so the diameter should be matched directly to the bend and flue system being used.
Suitability
The Schiedel ICID Locking Band for Bends is intended for 125mm or 150mm ICID twin wall chimney installations where a structural locking band is required to secure a bend connection.
Installation / Technical Notes
The band is used to secure the twist-lock bayonet jointing system on ICID bends. Select either the 125mm (5″) or 150mm (6″) version according to the internal flue diameter of the corresponding bend.
