SSCCBL segmented collar saddles allow fabricating round duct branches at the ductwork points that can only be defined when the main ventilation ducts have been installed. The collar saddle is installed by cutting an opening to match in round spiral or plain duct and fastening the piece with rivets or self-drilling screws. The joint edges need to be sealed with a silicone or acrylic compound. The saddle's form improves the air flow compared to standard collar saddles.
This product is specifically recommended for branching systems that require air tightness class D according to EN 12237.
