Details

The Keystone XCFS/K-50 Extra Heavy Duty Cavity Wall Lintel at 3600mm length is engineered for builders and contractors requiring robust support for wide cavity wall openings. Designed specifically for cavity widths between 50 and 65mm, this lintel delivers reliable load-bearing performance on demanding structural projects.
