Details

The Keystone X/K-50 Extreme Duty Cavity Wall Lintel at 3000mm is built for demanding structural openings where heavy loads must be supported reliably. Designed specifically for builders, site managers, and contractors working with cavity walls of 50-65mm, this lintel provides the strength and durability essential for serious projects. Please note, to achieve the specified load capacities, the lintel must be laterally restrained and propped during installation.

Application

This lintel is ideal for supporting openings such as doors and windows in cavity walls where extreme load conditions exist. Its galvanised steel flange offers corrosion resistance on the outer leaf, making it suitable for external walls exposed to weather. Propping during installation is recommended to speed up construction while maintaining structural integrity. Always ensure the lintel is installed with lateral restraint as per project requirements.
