The AB Tools Type 4 Cavity Wall Tie is designed for professional builders and masonry contractors who require a reliable, corrosion-resistant solution for cavity wall construction in residential and commercial buildings up to 10 metres high. Its key benefit is the integration of high-grade 304 stainless steel and a double drip feature that prevents moisture migration across the cavity; however, users should ensure the 225mm length specifically matches their cavity width requirement of 76-100mm to ensure structural compliance.

This specific model is designed for cavity widths ranging between 76mm and 100mm.
Yes, the grade 304 stainless steel provides excellent corrosion resistance, making it suitable for most environments, including coastal areas.
No, these specific Type 4 ties are rated for use in buildings up to 10 metres in height.
The double drip design interrupts the flow of moisture across the tie, preventing water from traveling from the outer wall to the inner wall.
Yes, the product is compliant with BS EN 845-1, which is the standard for masonry accessories.
Each pack contains 100 individual wall ties.
Ensure the mortar bed is of the correct ratio and that the tie is pressed firmly into the wet mortar to ensure full surface coverage.
Verify that you are using the correct fixing component for the timber frame side and that the embedment depth meets the specific structural design specifications for your project.
For proper installation, ensure that the masonry units are clean and that the mortar bed is of the correct thickness and strength. Embed the tie firmly into the mortar, ensuring the drip portion of the tie hangs freely within the air gap between the two walls to function as intended. Compatibility is broad, covering standard blockwork, timber frame stud work, and steel framing systems. No special maintenance is required once the wall is finished, thanks to the inherent properties of the 304 stainless steel, which maintains its integrity indefinitely under normal building conditions.
