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