robust, tear-resistant surface to prevent damage during the construction phase, this serves to avoid structure-borne sound bridges
reduced material thickness of 13 mm for space-saving installation to ensure clean, visible fire and smoke-tight filling of the component due to the larger intermediate distances from sleeve to sleeve.
simple and fast processing thanks to a tool-free quick-release fastener to reduce processing times.
Internal sliding film to ensure the sleeve's ability to slide on the pipe for quick assembly and to prevent operating noise.
