Details

The Keystone CFS/K-50 Extra Heavy Duty Cavity Wall Lintel, measuring 2700mm in length, is engineered for builders and site managers requiring dependable structural support for cavity walls with widths of 50-65mm. Designed specifically for heavy load applications, it’s a smart choice for serious projects where reliability and compliance are critical. Please note, all joints must be fully mortared, and lintels should be propped during installation to ensure stability and speed.

Application

This lintel is ideal for use in cavity walls where openings require extra heavy duty support, such as large window or door frames in residential, commercial, or industrial builds. It provides a strong structural bridge over cavities, distributing load evenly across the wall. Builders should apply a mortar bed on top of the blockwork before laying floor units to achieve uniform load distribution and maintain structural integrity.
