These Lynx U Shaped Wall Ties are heavy duty masonry cavity ties designed for a maximum cavity width of 120mm. Supplied as a pack of 25 galvanised, red coated wire ties, they provide a strong, dependable connection across wider cavities, keeping masonry leaves tied together for a stable, well built wall. Classified as Type A, masonry cavity, heavy duty ties, they suit construction where a wider cavity of up to 120mm is required, such as insulated or wider cavity walls. The galvanised wire carries a corrosion resistance rating of R3 for good durability in typical building environments, and the ties comply with AS/NZS 2699.1 (2000) for masonry connectors. The U shaped form is built into the mortar bed joints as the wall is laid, keying into the mortar to hold securely once cured. Robust and easy to place, these heavy duty ties are a reliable choice for bricklayers and builders working on wider cavity masonry. Each pack contains 25 ties, ready to space out along the bed joints as the courses are built up.
