Details

The Keystone CFS/K-90 WIL 4800mm lintel is a specialist extra heavy duty cavity wall lintel, engineered to support structural openings in walls with cavity widths between 90 and 105mm. Ideal for builders, contractors, and site managers working on demanding projects, it provides dependable strength where wide inner leaf blockwork of 125-150mm is used. Please note that all dimensions and recommendations should be followed carefully for optimum performance.

Application

This lintel is primarily used in cavity wall construction where a wide inner leaf is present, typically in residential or commercial blockwork walls. It supports openings such as windows and doors, transferring loads safely above these structural gaps. Installation best practice includes propping the lintel to facilitate faster construction and ensure stability during the build process. Blockwork should be built tight against the inner face of the lintel, with a mortar bed placed on top before laying floor units to distribute loads evenly.
