Casting mounting


The casting anchors are installed during the production of prefab concrete elements.



Saves time


Installation at the construction site is no longer needed.



Thermal decoupling


The plastic casing of the universal flex plug prevents direct contact between the cavity wall tie and the inner wall leaf and therefore also prevents a thermal bridge from forming.



To prevent personal injury


The cavity wall tie can be inserted into the universal flex plug at a later stage during the masonry work. This means that there are no protruding parts on the outside of the structure that can cause personal injury during the construction project.

NoticeWürth and GB encourage the use of sustainable materials and advise using A4 stainless-steel cavity wall ties in outer walls. This is supported by the Dutch Buildings Decree 2012/Eurocode 6.

  • Correct length of casting anchor = insulation thickness + depth of casting in inner cavity wall (40-60 mm).

  • Correct length of UNI impact cavity wall tie 4 mm diameter = length of casting anchor + air cavity + depth of insertion in outer leaf (45-75 mm).
