This cavity wall lintel from Keystone Lintels Ltd is designed for installation over structural openings in brick and block construction. Manufactured from galvanised steel, it provides a robust support across a cavity width of 70 to 85mm, accommodating a range of wall constructions on commercial and domestic projects.
The 3900mm length allows for larger spans over doorways, windows, or structural openings. Suitable for use with an inner leaf of 125–150mm and an outer leaf of 102mm, it is typically selected for general building where a standard duty lintel is required.
