Details

The Keystone CFS/K-70 WIL 3150mm lintel is a specialist extra heavy duty cavity wall lintel engineered to support openings in walls with cavity widths between 70 and 85mm. It is tailored for use with 125-150mm wide inner leaf blockwork, making it a trusted choice for builders and contractors working on demanding structural builds. Please note, the inner leaf block should not overhang the lintel flange by more than 25mm to ensure proper load distribution.

Application

This lintel is ideal for cavity wall construction where a strong, durable support is needed over openings such as doors and windows. Its extra heavy duty rating provides peace of mind on projects requiring high load-bearing capacity. The product is commonly used in residential and commercial developments with wide inner leaf blocks. For best results, lintels should be propped during installation to assist in faster and safer construction. Blockwork must be built tight against the inner face of the lintel, with a mortar bed applied on top before laying floor units to evenly distribute the load.
