Details

The Keystone S/K-150 WIL Standard Duty Cavity Wall Lintel at 3750mm length is a specialist structural support designed for builders and contractors working with cavity walls between 150 and 165mm wide. Suited for use with 125-150mm wide inner leaf blockwork, this lintel offers dependable load-bearing capacity for typical openings in residential and commercial projects. Please note, inner leaf blockwork should not overhang the lintel flange by more than 25mm to ensure correct installation. For any questions or technical clarifications, consulting the Keystone Technical Office is advised.

Application

This lintel is intended to provide strong support over openings such as windows and doors in cavity wall constructions featuring a wide inner leaf. Its standard duty rating makes it suitable for everyday structural demands encountered on site, supporting masonry loads while maintaining wall integrity. Propping lintels during installation is recommended to facilitate safe, efficient construction and to ensure full load transfer once the masonry has cured.
