Details

The Keystone CFS/K-50 WIL 4200mm lintel is engineered for extra heavy duty applications in cavity walls with a wide inner leaf. It provides reliable structural support for openings where cavity widths range from 50 to 65mm and is designed specifically to accommodate 125-150mm thick inner leaf blockwork. This lintel is the trusted choice for builders and site managers focused on strength and durability in demanding projects.

Application

This lintel is ideal for supporting window and door openings in cavity wall constructions where a wide inner leaf is present. It is particularly suited to projects requiring robust load-bearing capacity, such as commercial or residential developments with heavy masonry. To ensure optimal performance, the inner leaf blockwork should be built tightly against the lintel’s inner face, with no more than 25mm overhang beyond the flange. Proper propping during installation is recommended to facilitate a faster and safer build.
