This extra heavy duty cavity lintel from Keystone Lintels Ltd is constructed from galvanised steel and measures 4200mm in length with a height of 229mm. Designed to support masonry loads above structural openings, it is compatible with cavity widths between 70mm and 85mm.
Typically used in external walls where additional load-bearing strength is required, this lintel suits a range of cavity wall constructions. Its robust design allows for installation across wider openings while supporting both inner and outer leaf masonry during building projects.
