Details

The Keystone S/K-50 WIL 1800mm lintel is a standard duty cavity wall lintel engineered for builders and developers working with cavity widths of 50 to 65mm. Ideal for use with 125-150mm wide inner leaf blockwork, this lintel offers dependable structural support for openings in load-bearing walls. Please note that the inner leaf block must not overhang the lintel flange by more than 25mm to maintain integrity.
