This extra heavy duty cavity lintel from Keystone Lintels Ltd is designed for use in general building projects requiring support over structural openings. Manufactured from galvanised steel, it provides a robust solution for load-bearing applications where both an inner leaf (125–150mm) and an outer leaf (102mm) require reliable support.
At 2850mm in length, the lintel is suitable for wide openings, such as those for larger windows or doorways in cavity wall construction. It is typically installed by bricklayers or builders on site as part of the wall’s structure to maintain integrity above structural gaps, ensuring safe and stable distribution of loads from above.
