Product Information

Full details

The AB Tools Type 4 Cavity Wall Tie is designed for construction professionals and DIY enthusiasts who need a reliable, rust-resistant solution for connecting masonry leaves in residential or small-scale commercial buildings. These ties provide essential structural integrity for projects up to 10 metres in height, effectively managing moisture thanks to an integrated drip feature. While they offer exceptional durability due to their stainless steel construction, users must ensure the 200mm length is compatible with their specific cavity width of 50mm to 75mm before installation.

FAQs

Are these ties suitable for coastal environments?

Yes, because they are manufactured from grade 304 austenitic stainless steel, they offer excellent resistance to the salt and moisture found in coastal areas.

Can I use these for a wall taller than 10 metres?

No, these ties are specifically rated for structures up to 10 metres high. For taller buildings, consult a structural engineer for appropriate specifications.

What is the purpose of the double drip?

The double drip acts as a barrier to stop water traveling from the outer leaf to the inner leaf, preventing damp patches inside the building.

How many ties come in a pack?

Each pack contains 10 units.

Are these compatible with timber frames?

Yes, these are designed to be compatible with timber frames, stainless steel frames, and traditional block walls.

Can I use these in a 40mm cavity?

No, these are specifically designed for cavity widths between 50mm and 75mm.

Troubleshooting

Tie feels loose in the mortar joint

Ensure the mortar mix is of the correct consistency and that the tie is embedded at least 50mm deep.

Difficulty positioning the tie

Verify the cavity width is strictly between 50mm and 75mm. If the gap is outside this range, this tie size is incompatible.

Pros and Cons

Pros

  • Superior resistance to corrosion due to 304 grade stainless steel
  • Moisture-proof design prevents damp issues in masonry
  • Suitable for a variety of frame types including timber
  • Standardized 200mm size fits common cavity widths

Cons

  • Not suitable for buildings exceeding 10 metres in height
  • Limited to specific cavity widths of 50mm to 75mm
  • Requires precise installation to ensure proper moisture drainage

Setup, Compatibility & Care

To ensure structural integrity, always follow local building regulations regarding the spacing and vertical/horizontal placement of wall ties.

Compatibility:

  • Wall Types: Traditional masonry, timber frame, and stainless steel frame systems.
  • Cavity Width: 50mm to 75mm.
  • Building Height: Up to 10 metres.

Installation Tips:

  • Ensure the ties are embedded at least 50mm into the mortar of the inner leaf.
  • Keep the cavity clean of mortar droppings, as these can bridge the gap and bypass the moisture-drip feature.
  • Use a professional mortar mix that adheres correctly to stainless steel for a strong bond.
