Details

The Keystone X/K-90 Extreme Duty Cavity Wall Lintel at 3000mm length is built for builders and contractors tackling heavy structural loads over cavity walls with widths between 90 and 105mm. This lintel is a reliable choice where strength and durability are essential, supporting large openings in load-bearing masonry. Please note that lintels require proper lateral restraint for full load capacity and it is advisable to prop them during construction for safe and efficient installation.

Application

Designed specifically for cavity wall construction, this lintel supports extreme loads above window and door openings where cavity widths fall within 90-105mm. It is particularly suited to commercial and residential projects where heavy structural demands are placed on masonry openings. The galvanised steel flange protects the outer leaf from corrosion, extending the lintel’s service life in exposed conditions.
