The Keystone S/K-70 Standard Duty Cavity Wall Lintel, measuring 4350mm in length, is engineered for builders and contractors needing dependable support over openings in cavity walls with widths between 70mm and 85mm. Its robust design ensures reliable load distribution for standard structural applications. Please note, mortar bedding and propping are essential for correct installation.

Application

This lintel is typically used in cavity wall construction to span openings such as doors and windows where the cavity width falls within the 70mm to 85mm range. It supports the masonry above, transferring loads safely to the surrounding structure. Builders should ensure blockwork is tightly built against the lintel’s inner face and that a mortar bed is applied on top of the blockwork prior to laying floor units, providing even load distribution. Propping the lintel during installation is recommended to maintain site efficiency and structural safety.
