Details

The Keystone HD/K-70 Heavy Duty Cavity Wall Lintel at 3450mm is engineered for builders and site managers needing a reliable lintel solution for cavity walls with widths from 70 to 85mm. Its robust design supports heavy loads, making it a smart choice for serious construction projects.

It is suited to cavity widths between 70mm and 85mm, commonly found in modern cavity wall constructions.
