AB Tools Stainless Steel Type 4 Cavity Wall Tie - 200mm - 50-75mm - 5Pk

A cavity wall tie's primary function is to connect and secure the inner and outer masonry leaves of a cavity wall, providing structural stability and preventing them from moving independently.

'Type 4' typically refers to a specific design standard or configuration of wall tie, often related to its shape, material, and intended use in cavity wall construction, as defined by relevant building standards like BS EN 845-1.

No, these ties are specifically rated for buildings up to 10 meters in height, according to BS EN 845-1. Taller structures may require different types of wall ties designed for greater loads and environmental stresses.

The spacing of wall ties depends on building regulations, wall construction, and exposure conditions. Typically, they are installed at intervals of approximately 450 mm horizontally and 300 mm vertically, but always consult local building codes or a structural engineer for precise requirements.

The double drip feature is designed to create two points where condensation or water ingress can drip down within the cavity, preventing it from bridging the gap and travelling across to the inner leaf of the wall, thus reducing the risk of damp.

Yes, grade 304 stainless steel is known for its excellent corrosion resistance and is widely used in outdoor applications, including construction, where it is exposed to varying weather conditions.

This particular wall tie is designed for a cavity width range of 50 mm to 75 mm.

Verify the cavity width measurement. This tie is designed for 50-75mm cavities. If the cavity is outside this range, a different size tie may be required.

Ensure the double drip feature is correctly oriented and not blocked by mortar. Confirm that the ties are installed at appropriate intervals and that the overall building's weatherproofing (e.g., DPC, membrane) is intact.

The austenitic stainless steel is malleable. Apply gentle pressure to shape the tie as needed to fit the cavity and engage securely with both masonry leaves.
