Details

The Keystone CFS/K-70 WIL 2550mm lintel is engineered for builders and contractors requiring robust, extra heavy duty support for cavity walls with wide inner leaf blockwork. Its design accommodates cavity widths between 70 and 85mm, supporting inner leaf blocks sized 125-150mm. This lintel ensures strong, dependable load bearing for critical openings in structural masonry.

Application

This lintel is ideal for use in cavity wall constructions where a wide inner leaf is present. It is specifically suited to load-bearing openings such as doorways and large window frames, where additional strength is essential. The lintel should be installed with the inner leaf blockwork built tight against its inner face, with no more than 25mm overhang beyond the flange to ensure proper support. To optimise build speed and structural integrity, propping the lintel during construction is recommended.
