AB Tools Stainless Steel Type 4 Cavity Wall Tie - 225mm - 76-100mm - 10Pk

Cavity wall ties are used to connect the inner and outer masonry leaves of a cavity wall, providing structural stability and preventing the walls from separating.

Type 4 generally refers to a specific design and standard of wall tie, often related to its intended use, material, and connection method. This type is suitable for buildings up to 10m high.

No, these specific wall ties are designed and rated for buildings up to 10m high and compliant with BS EN 845-1 for that height. Taller structures may require different types of wall ties.

Each pack contains 10 cavity wall ties.

The double drip feature is designed to prevent moisture from travelling across the cavity from the external wall to the internal wall, helping to avoid dampness and associated problems.

These specific ties are designed for cavity widths ranging from 76mm to 100mm. Ensure your project's cavity width falls within this range.

The ties are made from Grade 304 18/8 austenitic stainless steel, known for its excellent corrosion resistance.

Ensure the tie was fully embedded in the mortar of both masonry leaves during construction. Verify correct cavity width was used. If the issue persists, consult a structural engineer.

Check that the double drip feature is correctly oriented to divert water downwards. Ensure no gaps exist around the tie where it enters the masonry. Verify DPC (Damp Proof Course) and BPC (Breathable Protective Course) are correctly installed.

Grade 304 stainless steel is highly resistant to corrosion. If corrosion is observed, it may indicate contact with dissimilar metals or aggressive environmental contaminants. Inspect surrounding materials for issues.
