This heavy duty cavity lintel from Keystone Lintels Ltd is made from galvanised steel and measures 1650mm in length. Designed for use in cavity wall construction, it features a profile suitable for supporting masonry over clear openings in both new builds and extension projects.
The lintel is typically used over doors, windows, and other structural openings where a robust solution for supporting brickwork is required. Its compatibility with cavity widths of 50–65mm and varied leaf sizes means it is suited to a range of standard cavity wall build-ups on site.
