Details

The Keystone CFS/K-90 Extra Heavy Duty Cavity Wall Lintel is engineered specifically for builders and contractors requiring a robust support solution for cavity walls with widths between 90mm and 105mm (3.5"-4.1"). With a length of 4800mm (15ft 9in), this lintel delivers reliable strength and stability for demanding structural openings. Please note that all joints must be mortared and lintels propped during installation for optimal performance.
