Details

The Keystone CFS/K-70 WIL is an extra heavy duty cavity wall lintel, purpose-built for wide inner leaf blockwork measuring 125-150mm. It’s ideal for builders and contractors working on substantial openings where reliable load bearing is critical. Please note that the inner leaf block should not overhang the lintel flange by more than 25mm to maintain structural integrity.

Application

This lintel is designed to support cavity walls with a cavity width ranging from 70mm to 85mm, making it suitable for robust masonry projects such as large window or door openings. It’s commonly used where heavy loads are expected above wide inner leaf blockwork and helps ensure stability and durability on site. For efficient construction, it’s recommended to prop the lintel during installation and build blockwork tightly against the inner face of the lintel.
