This Keystone extra heavy duty cavity lintel is designed for supporting structural openings in cavity wall construction. Manufactured from galvanised steel, it is suitable for cavity widths between 90mm and 105mm, covering a range of masonry types.
The lintel’s 3300mm length makes it fit for large span openings where substantial load-bearing is required. Installation is common across both residential and commercial sites, providing support above doors, windows, or similar apertures in double-leaf wall construction.
