Details

The Keystone CFS/K-90 WOL 3900mm lintel is an extra heavy duty cavity wall lintel engineered for construction projects requiring strong, dependable support over wide openings. Suited for builders, site managers and contractors working with 90-105mm cavity widths and 125-150mm outer leaf blockwork, this lintel offers reliable structural integrity on demanding builds. Please note, images are for illustration only and installation guidance should be followed carefully.

Application

This lintel is designed for cavity wall construction where a wider outer leaf is used, typically 125-150mm thick blockwork. It supports openings such as windows and doors, ensuring load is safely distributed above the cavity. The lintel flange must not be overhung by more than 25mm to maintain structural performance. Propping the lintel during build is advised to facilitate quicker and safer construction progress. Mortar bedding on top of the blockwork before laying floor units helps achieve an even load distribution.
