Keystone S/K-70 WIL Standard Duty Cavity Wall Lintel 2700mm

The Keystone S/K-70 WIL is a reliable standard duty cavity wall lintel, designed specifically for wide inner leaf blockwork projects. Ideal for builders and site managers working on cavity walls with 70-85mm cavities, this lintel offers dependable support for openings where 125-150mm inner leaf blocks are used. Please note the inner leaf block should not overhang the lintel flange by more than 25mm to maintain structural integrity.

Application

This lintel is typically installed above doors, windows, and other wall openings within cavity walls featuring a wide inner leaf. It supports the masonry above the opening, ensuring load distribution across the cavity and inner leaf. Its standard duty rating makes it suitable for most residential and light commercial developments where cavity widths fall within the specified range. To ensure safe and efficient construction, it is advisable to prop the lintel during installation.
