This Keystone Extreme Load lintel is designed for supporting cavity wall construction over structural openings, measuring 4350mm in length. Manufactured from galvanised steel, it is specified for heavy-duty applications in both domestic and commercial projects where a robust load-bearing solution is required.
Suitable for cavity widths between 50mm and 65mm, this lintel provides reliable support for masonry walls with a 140-150mm inner leaf and a 102mm outer leaf. It is typically installed in situations requiring a long clear span and substantial end bearing, such as wide doorways or openings in thick cavity walls.
