Details

The Keystone S/K-150 WIL standard duty cavity wall lintel is engineered to provide dependable support for openings in cavity walls with widths of 150-165mm. Ideal for builders and contractors working with 125-150mm wide inner leaf blockwork, this lintel combines practical design with robust performance to meet the demands of serious construction projects. Please note that the inner leaf block should not overhang the lintel flange by more than 25mm to ensure proper load distribution.

Application

This lintel is suited for use in cavity wall constructions requiring a wide inner leaf support, commonly found in residential and commercial building projects. It is typically installed above window and door openings to carry the structural load safely across the cavity. Propping is recommended during installation to speed up construction and guarantee stability until the lintel is fully supported by surrounding masonry.
