Details

The Keystone CFS/K-50 Extra Heavy Duty Cavity Wall Lintel is engineered for builders and contractors requiring robust support for large openings in cavity walls with widths of 50-65mm. At 3900mm long, this lintel is built to handle demanding loads, making it a reliable choice for structural integrity on serious construction projects. Please note, all perpendicular and horizontal joints must be fully filled with mortar during installation to ensure optimal performance.

Application

This lintel is ideal for use above doorways, windows, and other wall openings in cavity wall constructions where extra heavy duty load support is essential. It suits both residential and commercial builds where cavity widths range from 50 to 65mm, providing consistent strength and durability. For best results, apply a mortar bed on top of the blockwork prior to laying floor units to evenly distribute the load. Propping the lintel during installation is recommended to speed construction and maintain safety.
