These 300mm ties are specifically designed for cavity walls ranging from 151mm to 175mm in width.
These are rated for buildings up to 10 metres in height, which generally covers typical two-story residential homes.
No, they are manufactured from Grade 304 stainless steel, which is highly resistant to rust and atmospheric corrosion.
Yes, these ties are compatible with timber-framed, stainless steel-framed, and traditional block wall structures.
The drip design is intended to stop water from traveling across the wall tie, preventing moisture from reaching the inner wall leaf.
This specific pack (MPN: FN109_50PK) includes 50 individual wall ties.
Ensure the mortar joint is clean and free of hardened debris; use a mortar tool to clear the slot if necessary.
Verify that ties are installed with the drip feature facing downwards and that no mortar bridging exists on the tie.
To ensure proper performance, verify that the wall cavity measures between 151mm and 175mm before installation. For masonry construction, embed the tie at least 50mm into the mortar bed. These ties require no specific maintenance once installed, as the 304 stainless steel naturally resists atmospheric corrosion. When storing unused ties, keep them in a dry environment to ensure they remain clean and free from construction debris or site contaminants that could affect the bond quality.
