Details

The Keystone S/K-90 is a standard duty cavity wall lintel measuring 3900mm in length, engineered to provide dependable support for masonry openings in cavity walls with widths of 90-105mm. This lintel is suited to builders and site managers seeking a proven solution to structural openings in blockwork walls. Please note that blocks are built tight against the lintel’s inner face, and correct installation practices should be followed.
