Details

The Keystone CFS/K-110 WIL 3900mm lintel is a specialist extra heavy duty cavity wall lintel engineered for wide inner leaf blockwork projects. It’s designed specifically for builders, contractors, and site managers who require robust, reliable support over openings in cavity walls with inner leaf widths between 125-150mm. Please note, this lintel must be installed with attention to proper support and positioning to achieve its full load-bearing capacity.

Application

This lintel is ideal for structural openings such as windows and doors within cavity walls where the inner leaf blockwork ranges from 125mm to 150mm wide. The lintel safely carries heavy loads, making it suitable for demanding residential and commercial construction projects. To ensure optimal performance, it is important to prop the lintel during installation and build the blockwork tightly against the inner face of the lintel flange. A mortar bed should be placed on top of the blockwork before installing floor units, which aids in even load distribution.
