This extra heavy duty cavity lintel from Keystone Lintels is designed for supporting masonry over structural openings in cavity wall construction. Manufactured from galvanised steel, it is suitable for applications where robust load-bearing capacity is needed above doors, windows, or similar apertures.
With a 4000mm length and compatibility for cavity widths between 70mm and 85mm, it fits a variety of build requirements. The lintel is typically installed in new build or refurbishment projects by bricklayers and contractors, providing support across both inner and outer leaves of cavity walls.
