Details

The Keystone X/K-70 Extreme Duty Cavity Wall Lintel at 3000mm length is specifically designed for builders and contractors handling heavy structural loads in cavity walls with widths from 70 to 85mm. Built to deliver reliable, long-lasting support for large openings, this lintel is an essential component for serious construction projects where strength and durability are critical. Please note, the lintel must be laterally restrained to achieve its full loading capacity.

It is particularly suited to commercial or residential projects where structural integrity cannot be compromised. To maintain safety and work efficiency, it is recommended to prop the lintel during installation, accelerating the build process without sacrificing strength.
