Application

This lintel is ideal for use in cavity wall construction, supporting brick or blockwork over window and door openings. It provides a solid bearing surface to distribute loads evenly across the cavity, ensuring structural integrity. The lintel's design allows blockwork to be built tightly against its inner face, with a mortar bed applied on top before floor units are laid to optimise load transfer. Propping is recommended during installation to maintain speed and safety on site.
