The Keystone CFS/K-70 WIL 4350mm lintel is engineered for extra heavy duty cavity wall applications, ideal for builders, contractors, and site managers working on large-scale or demanding masonry projects.

Please note that the inner leaf block should not overhang the lintel flange by more than 25mm to maintain structural integrity.

This lintel is perfectly suited for use in cavity wall constructions requiring wide inner leaf support, such as residential and commercial openings including windows and doors.
