Wedge Anchor is a very easy-to-apply accessory which can be used as a best solution for Knauf Ceiling systems (RCS and D112 with Nonius Hangers), perimeter fixings for ceilings, and even for partitions where fire resistance is required. Wedge Anchor is faster alternative to the ceiling steel dowel in case of RCS Ceiling systems and FR rated alternative to Plastic Plug & Screw in terms of fire rated partitions.
