Details

The Keystone X/K-50 Extreme Duty Cavity Wall Lintel is engineered for builders and contractors tackling heavy structural loads in cavity wall construction. At 4500mm long, this lintel is designed to support large openings where cavity widths range from 50 to 65mm. Please note that lintels must be laterally restrained and propped during installation to meet loading requirements and ensure safe, reliable use.

Application

This lintel is ideal for use in demanding cavity wall projects, such as supporting large window or door openings in residential or commercial developments. Its extreme duty rating makes it suitable for sites requiring robust structural support where reliability and compliance with building standards are critical. The galvanised steel flange protects the outer leaf against corrosion, extending the lintel’s lifespan on site.
