This Keystone extra heavy duty cavity lintel is constructed from galvanised steel and measures 1950mm in length, making it suitable for use in supporting structural openings within cavity wall construction.
Designed for installation across openings in both internal and external walls, the lintel is compatible with cavity widths of 70–85mm. It is typically applied on-site to provide a stable base for brickwork or blockwork, accommodating varying leaf thicknesses for both inner and outer leaves.
