This Keystone cavity lintel is designed for use in masonry cavity wall construction where higher load requirements are present. Manufactured from galvanised steel, it measures 4000mm in length, 308mm in width, and 234mm in height, making it suitable for wider openings and structural applications that demand extra support.
Typically installed in external walls, it is compatible with cavity widths of 90-105mm and fits an inner leaf of 125-150mm and an outer leaf of 102mm. This lintel is commonly used on site to bridge structural openings such as doors and windows, providing reliable support in demanding building situations.
