This cavity wall lintel from Keystone is constructed from galvanised steel and measures 4000mm in length. Designed for extreme load applications, it is suitable for masonry with an inner leaf width of 140-150mm and an outer leaf width of 102mm. The lintel is compatible with cavity widths between 50mm and 65mm, making it a practical solution for larger structural openings in cavity wall construction.
On site, the lintel is typically installed to provide support above door or window openings where high load capability is required. Its extended length and robust construction accommodate challenging loads, while the cavity design enables seamless integration into both new build and extension projects involving wider wall sections.
