Details

The Keystone CFS/K-90 WIL 750mm lintel is an extra heavy duty support designed specifically for cavity walls with wider inner leaf blockwork. It provides dependable load-bearing capacity for large openings, making it a trusted choice for builders, contractors and site managers handling demanding masonry projects. Please note that the inner leaf blockwork must not overhang the lintel flange by more than 25mm and appropriate propping is recommended during installation to maintain construction efficiency.

Application

This lintel is tailored for cavity wall construction where the cavity width ranges between 90mm and 105mm, with inner leaf blockwork thickness of 125mm to 150mm. It is ideal for supporting structural openings such as windows and doors in residential and commercial buildings requiring extra heavy duty load capacity.
