Robust, tear-resistant surface to prevent damage during the construction phase, this serves to avoid structure-borne sound bridges.

Easy and quick processing due to tool-free quick-release fastener to reduce processing times.
Inner sliding film to ensure the collars can be moved on the pipe for quick assembly and to prevent operating noise.
