Details

The Keystone CFS/K-110 WIL 4350mm lintel is an extra heavy duty support designed specifically for cavity walls with a wide inner leaf. Trusted by builders and site managers, it ensures robust load-bearing capacity for critical structural openings where reliability and stability are essential. Please note, inner leaf blockwork must not overhang the lintel flange by more than 25mm, and lintels should be propped during installation to speed up construction and maintain safety.

Application

This lintel is ideal for use in cavity wall construction where the cavity width ranges from 110mm to 125mm, supporting inner leaf blockwork widths of 125mm to 150mm. It is particularly suitable for heavy-duty projects requiring strong structural support above openings such as doors and windows. Builders typically use this lintel when working with wide inner leaf blockwork to maintain wall stability and distribute loads evenly.
