Details

The Keystone CFS/K-150 WOL 3900mm lintel is a specialist extra heavy duty cavity wall lintel designed for trade professionals managing wide cavity walls between 150-165mm. This lintel is purpose-built to support substantial blockwork loads on outer leaf widths of 125-150mm, providing dependable structural integrity on demanding building projects. Please note, the outer leaf blockwork should not overhang the lintel flange by more than 25mm to maintain performance standards.

Application

This lintel is typically used by builders, site managers, and contractors for cavity wall openings such as windows and doors that require robust support. It is well suited to residential and commercial developments where extra heavy duty load-bearing capacity is essential. Proper installation includes propping the lintel during construction to enable safe load transfer and to accelerate build times. Additionally, blockwork should be built tight against the lintel’s inner face, with a mortar bed applied on top before laying floor units to ensure even load distribution.
